CHANGELOG

A Frogger variant where you ferry cargo back and forth across an industrial canal that dies a little more with each crossing. The outbound trip is planning. The return trip is consequences. Every crossing poisons the river, and every return trip forces you through the wreckage you just made. Grid-based committed movement, 5 river lanes with sinking logs, 4 traffic lanes with vehicles, per-crossing timer that tightens with deliveries, bidirectional crossing state machine, pollution escalation system (log sink levels 0-3, water color shift, vehicle speed increase, timer tightening), committed hop animation with squash/stretch, procedural audio with industrial drone that thickens with pollution harmonics, ferryman aesthetic with industrial decay.

A horizontal-scrolling space shooter inspired by Gradius III, featuring the strategic power-up bar system where players collect capsules, cycle through upgrades (Speed Up, Weapon, Option, Shield), and choose when to cash in. Death strips all power-ups, creating a tense escalation-and-loss loop. 4-slot Gradius-style power-up bar, 5 enemy types (basic fighter, swooper, formation flyer, capsule carrier, turret), 3 boss encounters with 2 phases each (Vanguard, Leviathan, Rift Core), parallax starfield, CRT-era arcade glow aesthetic with neon projectiles, 18 procedural audio SFX + boss drone ambience, particle effects, screen shake, freeze frames, muzzle flash.

A Missile Command reimagining where six named cities with visible populations and dimming light become the emotional center. Three defense bases with limited ammo, click-to-target counter-missile system with nearest-base auto-selection, chain-explosion mechanic with escalating visual/audio feedback, wave progression with escalating difficulty, wave-end interstitial with casualty reports and population regeneration, city destruction fade-to-dark animation with mournful audio. Somber visual identity: dark indigo sky with procedural stars, warm amber city lights, harsh white explosions. 10 procedural audio effects via Web Audio API.

A brick-breaking arcade game where same-colored bricks detonate in chain reactions when adjacent bricks are destroyed. The classic Breakout grid becomes a puzzle to read: aim for the right brick, and a single hit cascades into a screen-clearing avalanche of destruction. BFS flood-fill chain reactions on same-colored adjacent bricks, escalating cascade audio (rising pitch per chain link, resolution chord on completion), crystalline 4-layer brick rendering, neon-on-dark Geometry Wars aesthetic, combo counter, exponential chain scoring, 5 levels with escalating difficulty, and a 250ms signature moment freeze on 6+ cascades.

A vertical falling shooter inspired by Downwell where every shot creates a shockwave on impact, pushing enemies and nudging platforms. The player descends an endless well, using their gun as a weapon, brake, and spatial reshaping tool. A sonar-pulse aesthetic ties the visual identity to the core mechanic: you see by shooting. Canvas-based vertical scroller with gravity-driven falling, downward shooting with recoil, shockwave system applying radial force to nearby entities on impact, sonar-pulse visuals (expanding cyan rings illuminate the dark well), two enemy types (Walkers and Flyers), stomp mechanic, rising ceiling forcing continuous descent, procedural well generation with difficulty scaling, full procedural audio (shot crack, sonar thump, stomp crunch, ambient rumble), and art-directed visual polish (chiseled well walls, multi-ring sonar pulses with birth flash, enemy silhouettes, CRT-style bezel).

A text-based survival journey through a hostile, unknowable world. The player moves forward one decision at a time — fight or flee, rest or press on, eat or save. Every step costs something. There is no going back. Death is frequent, fast, and instructive. A Souls game compressed into text. 19 data-driven encounters across 3 difficulty tiers, full procedural Web Audio API soundscape (breathing ambient drone, percussive combat, deliberate silence), typewriter text presentation, and a Signature Moment (The Hunter) that rewards mastery through death.

Faithful recreation of the 1976 Exidy Death Race with modern audiovisual feel. Drive a car across an open field, run over gremlins for points, and watch each kill become a permanent tombstone obstacle. The field fills with your own success until navigation becomes a white-knuckle threading act through a graveyard you built. Tank-style car with weight, momentum, and drag-based deceleration. Gremlins with random-walk AI and tombstone avoidance. Permanent tombstone placement at every kill location — the core self-sabotaging mechanic. Full procedural audio: engine drone with LFO pitch modulation, gremlin hit composite, tombstone collision crunch, graveyard atmosphere drone that builds with tombstone count. Monochrome bone-on-charcoal visual identity with CRT scanline overlay, vignette, and phosphor glow effects.

Faithful recreation of the 1979 Atari Lunar Lander with modern audiovisual feel. Rotational thrust control, procedurally generated terrain with landing pads of varying difficulty and score value, limited fuel, and physics-based descent. The silence-roar-silence audio axis and vector-modern aesthetic are the differentiators. Dual-layer bandpass filtered white noise thrust, crash impact with layered thud+noise+ring+sawtooth, landing chime, ambient hum, fuel warning beep, level advance arpeggio, high score fanfare. Two-tier star field, Kai Lund art direction with Courier New typography, green/cyan HUD hierarchy, lander glow, terrain fill, pad bracket markers.

A submarine survival horror game where sonar pulses are your only vision, every torpedo reveals your position to hunting destroyers, and the ocean is dark. Based on the 1976 Midway arcade game, reimagined as atmospheric survival where silence is your best weapon. Canvas-based survival with sonar-as-vision mechanics. Triple-pass sonar ring rendering with phosphor decay and 100ms echo hold. 11+ procedural audio functions including layered sonar ping with echo return, stereo-panned propeller wash, proximity-modulated depth charge rumble, and 45/47Hz ambient beat-frequency drone. Signature moment: destroyer kill triggers explosion-as-sonar-pulse illuminating nearby ships, with rising audio sting and drone dip. CRT-aesthetic visual treatment: scanlines, edge vignette, depth gradient, phosphor green palette.

A maze-chase journey through four distinct worlds inspired by Ms. Pac-Man (1982). Each maze has its own color palette (blues, ambers, purples, reds), audio mood, and ghost aggression profile. Semi-random ghost AI replaces deterministic targeting, making pattern memorization unreliable. Moving fruit bounces through corridors. Four structurally distinct 28x31 maze layouts with compacted string encoding. Per-maze visual identity and audio identity with shifting siren frequencies, waka-waka tones, and sound effect timbres. 12+ procedural audio effects via Web Audio API. Signature Moment on first Maze 4 clear: sustained four-tone chord, 40 multi-colored particles, double flash.

A recreation of the 1982 Williams arcade classic with a rising lava twist. Players ride a flying ostrich and defeat enemy knights by jousting from above. Each wave the lava rises, swallowing platforms from the bottom up, compressing the arena into a desperate knife-fight in the sky. Flap-to-fly physics with gravity, impulse, momentum, and drag. 3 enemy tiers (Bounder, Hunter, Shadow Lord). Egg mechanic: defeated knights drop eggs that hatch into tougher knights if not collected. Rising lava swallows platforms each wave, with platform re-emergence between waves. CRT-dark visual aesthetic with entity glow, lava underlight, and procedural audio including 14 sound effects and lava ambient drone.

A side-scrolling platformer where a squirrel races through an autumn forest collecting nuts before winter arrives. 10 short, fast levels (15-30 seconds each) that progressively strip the forest bare — trees lose leaves, gaps widen, wind pushes you sideways — turning a cozy autumn romp into a desperate survival scramble. Auto-running squirrel with variable-height jump physics, coyote time, jump buffer, and auto-hop at branch edges. Full seasonal visual progression from warm gold/orange to near-monochrome gray/white. Wind system starting at level 5 with visual telegraph streaks. 13+ procedural audio effects including ascending nut-pitch ladder and background drone shifting from 80Hz to 60Hz. Signature moment on level 10: slow-mo into hollow, victory chord, sleeping squirrel surrounded by nuts.

Tetris with cascade/chain reaction mechanics. When a line clears, individual blocks fall independently under gravity, potentially triggering additional line clears in chain reactions scored exponentially (2^(N-1) multiplier). All 7 standard tetrominoes with SRS-lite rotation and wall kicks, ghost piece, next piece preview, DAS/ARR for smooth movement. Dark modern arcade aesthetic with vivid saturated block colors, beveled rendering, motion trails on cascade blocks, and per-chain-depth chromatic glow. Direct restart from game over for zero-friction retry.

A faithful recreation of the 1979 Namco Galaxian arcade shooter with modern game feel and CRT arcade cabinet aesthetic. 38-enemy formation (2 Red Flagships, 16 Purple Guards, 20 Blue Drones) with idle sway animation, Bezier curve dive attack paths, flagship escort mechanic for bonus scoring (150/200/800 points), and a single-bullet-at-a-time constraint. CRT visual treatment with scanline overlay, phosphor bloom, vignette, and enhanced sprites. 12 procedural audio events including formation hum. The gap in existing browser Galaxian clones is not missing mechanics — it is missing feel.

Hill climb racing reimagined as a dolphin riding ocean waves. Physics-based momentum game where you ride a bezier-curve dolphin over procedurally generated waves, managing angle and energy to travel as far as possible. The dolphin flows with the water — it curves, arcs, and flexes with angular velocity. Momentum physics on procedural sine-wave terrain with landing quality tiers (clean/okay/bad), flip tricks, combo chains, and a sunset-over-ocean visual identity. The ocean is not hostile — energy management is the only constraint.

A classic Pac-Man arcade clone with faithful ghost AI personalities (Blinky direct chase, Pinky 4-ahead ambush, Inky Blinky-reference flanking, Clyde distance-threshold shy), procedural audio, and modern game-feel polish. Navigate the maze, eat all dots, avoid (or devour) ghosts, and clear levels for a high score. Neon arcade aesthetic with per-element glow effects. The soundscape communicates game state — rising siren as dots deplete, waka-waka rhythm, signature moment on the 4th ghost chain eat.

A vertical-scrolling shmup where your ship has mass. Thrust-based movement means every dodge is a commitment, every position earned through momentum. A shared energy resource powers both weapons and shield, creating continuous offense/defense tension. Cold industrial aesthetic — no background music, silence is the soundscape. 3 sectors, 14 waves, 3 bosses, and a signature moment of complete silence after the final kill.

A side-scrolling cave-flyer where a heavy military helicopter fights gravity through hostile underground caverns, destroying turrets and extracting hostages. Momentum physics make the helicopter feel like a real machine — thrust fights gravity, inertia fights precision. The rescue mechanic forces the player to become still in a game that punishes stillness. The rotor IS the music — no soundtrack, just a mechanical soundscape that shifts with every input.

A dark fantasy take on the Donkey Kong formula. A lone knight ascends a cursed tower, dodging flaming skulls and spectral hazards rolling down crumbling platforms, to free a captive chained at the summit. Classic arcade structure with modern game feel — weighty jumps, oppressive ambient drone, and a cathartic C-major victory chord. Each of the 3 levels has distinct platform geometry and escalating hazard difficulty.

A top-down action-adventure dungeon crawl inspired by The Legend of Zelda (1986). One complete dungeon experience: a small overworld hub leads into a 10-room dungeon with real-time sword combat, bomb puzzles, push-block mechanics, and a boss fight. NES-faithful pixel aesthetic with dark fantasy atmosphere. Enter, explore, solve, fight, claim the Triforce fragment.

A Wolfenstein 3D-style raycasting FPS in a single HTML file. First-person maze crawler through procedurally generated 16x16 dungeons using DDA raycasting, solid-color walls with distance fog fading to black, hitscan pistol combat against patrolling guards, key-locked doors, and 3 levels of escalating dread. Dark fantasy aesthetic with the Morten Mai palette — earth browns, stone greys, blood reds, muted gold HUD.

A zero-friction Sudoku puzzle with procedural audio feedback. Digits 1-9 mapped to a pentatonic scale, group completions trigger register-varied harmonic chords, and solving feels like finishing a piece of music. Warm-lamp-at-night aesthetic with pencil marks for Hard mode.

Tile-based RPG inspired by Ultima I: The First Age of Darkness. Procedurally generated 48x48 overworld with towns, dungeons, and fog of war. Turn-based bump-to-attack combat with 5 enemy types, 4-tier equipment, and XP/leveling. Collect three Gems of Power and storm Mondain's Dark Tower. Designed by Morten Mai persona.

Space Invaders with Claude Code terminal icons ("> _") as the invaders. Formation march with escalating tempo, segment-based shields that erode under fire, CRT phosphor-green aesthetic. The march beat IS the music — its tempo and sudden silence are the emotional arc.

Classic vector arcade shooter with Newtonian physics, screen wrapping, and wave escalation. Three asteroid sizes with split-on-hit behavior. Hyperspace teleport with 10% malfunction risk. Procedural audio: heartbeat bass pulse, thrust hiss, crunch cascade by size, ship death, wave fanfare.

Single-player browser Pong — player vs CPU with three difficulty tiers. Ball speed escalates +14 px/s per hit (280-560 px/s range), resetting on each point. Full juice: ball trail, paddle stretch, screen flash and shake on score. 9 procedural audio events.
