SPLIT
Your brain can’t do this.
Two thumbs, one brain. A fast coordination game about holding two rhythms at once — and the moment they fall apart.
Two thumbs, two lanes
The screen is split down the middle. Each half has an orb that hops between two rails. Tap the left half and the left orb flips; tap the right half and the right orb flips. Gates fall with one gap each — be on the right rail when they arrive.
Colour is the whole language of the game: is always the left hand, is always the right. Nothing else is asked of you.
Left thumb
Flips the left orb between its two rails. One tap is the move — no swiping, no holding.
Right thumb
Flips the right orb between its two rails. Same single tap, on its own beat.
The Desync Engine
Difficulty here does not come from speed or random obstacles. Each lane runs its own metronome, and the right lane is shifted a little out of phase with the left. As you survive, that shift grows: the two beats pull apart into a lopsided gallop, and your hands have to keep both at once.
That is the honest hook. It is not a claim about left-brain or right-brain dominance — that is a joke about a pop-science trope. What is real is bimanual independence: hands genuinely resist moving to two different rhythms, and this game is built to find the exact point where yours give up.
Every run ends with a verdict naming which side cracked first. Failure is the content.
