Retro Game Physics
Responsive gravity, tile collision grids, friction and jump velocity modeled after classic platformer feel.
A fully interactive 2D platformer powered by native JS physics and procedural Web Audio synthesizers. No plugins. No audio files. Pure web magic.
Responsive gravity, tile collision grids, friction and jump velocity modeled after classic platformer feel.
Zero audio network requests. Jumps, coins, stomps and melodies are generated live from oscillator nodes.
Patrollers walk, detect walls and ledges, respect collision boundaries and react to being stomped.
Fire up the real-time procedural sound generators. Every card below builds its waveform and envelope on the fly.
How does the sound synthesis work?
The Web Audio API instantiates transient oscillators, shapes their frequency curves and applies volume envelopes — every sound is computed at play time.
Can I play with a controller?
Use the arrow keys, A/D plus Space, or the on-screen retro D-pad optimized for touch devices.
