Otu
In OTU, you control a nimble triangle bound to a circular orbit. Your mission is simple: stay alive as long as possible. But the universe is against you! Spheres close in from the void, shrinking bars attempt to crush you, and lethal rotating lasers force you to keep moving. Think you’ve mastered the rhythm? Every 10 seconds, the game throws a Random Debuff at you. From screen-shaking earthquakes and inverted controls to pixelated vision and orbit shifts—no two runs are ever the same!
