DEFEND THE CORE. BUILD THE BEAT
Oscillon is a hypnotic arcade survival game with a built in music track editor. Build your own beat, hear your music rise and fall as you play.
BE THE COMPOSER

Want to curate your own vibe? Oscillon features built-in music track editor. Author your own chord progressions, program the drums, bass, and synth lines, and map out exactly how your bounce-triggers will sound.
Save your custom tracks, export them as WAV files to listen anywhere, or load them straight into your next run and defend the core to your own masterpiece.
CHOOSE YOUR FREQUENCY (FOUR MODES)
Whether you're looking for a punishing challenge or a zen audio-visualizer, Oscillon has a mode for your mood:
Survival: Pure, endless arcade defense. Earn credits, unlock persistent upgrades, and chase the top spot on the global leaderboards.
Vibe: No damage. No fail state. Just pure audio-visual zen. Sit back, spin the paddle, and lose yourself in the music.
Wave: A grueling 30-wave gauntlet. Draft cards between rounds. Survive to every fifth wave to face down brutal Boss waves that twist the rules of the game.
Challenge: Eight hand-crafted, masochistic skill tests. Tiny paddles, invisible balls, a one-HP core, and constant health drain. Prove your mastery.

CUSTOMIZE THE CHAOS
Upgrades: Seven upgrade branches to empower your future runs.
Push Your Luck: Equip Survival Mutator cards to trade higher difficulty for massive credit multipliers.
Visual Flair: Eight unlockable cosmetic skins that completely re-tint and shift the game's visualizer.
Accessibility First: Per-effect visual toggles, and a distinct three-channel audio mix so you can play your way.
