Collapse: Wave Puzzle

Collapse is a puzzle game about being seen — and unseen.

Your particle never stops moving. While you steer it, it is SOLID: walls stop you, and every observer can see you. Let go and it collapses into a WAVE: you drift straight through walls and detector beams, invisible — but you can't turn, and your coherence is running out.

Hold. Release. Re-grip. Every level is a question of when to be which.

• 20 handmade levels across two chapters • Mirrors that bend your drifting wave around corners • Watchers that sweep their light — hide behind walls, or slip through as a wave • Static fields that scatter waves, so some gaps can only be crossed solid • Hidden shards in most levels: collect them all for the third star • A brand-new daily challenge every day, with streaks • Checkpoints on the longest levels, and a coach that teaches the basics • Simple one-thumb controls, made for landscape play • Fully offline. No ads, no accounts, no tracking — ever.

Be a wave. Be a particle. Don't get seen.
