Stellar Drift

An endless space survival game — made entirely by AI, coded in pure Java + Android Canvas API. No game engine. No bitmaps. Every pixel is drawn programmatically.

🎮 About

Stellar Drift is an infinite space dodging game where you pilot a neon-lit spacecraft through asteroid fields, collect stardust, and survive as long as possible.

The entire game — graphics, sound effects, and UI — is created using nothing but code.

No external assets. No sprites. No audio files.

Every visual element is rendered in real time using Android's Canvas API (Path, Paint, LinearGradient, RadialGradient) and mathematical functions.

Every sound effect is synthesized programmatically using AudioTrack and sine waves.
