Spin Blast

A timing game dressed as a shooter. A target rotates in front of you, you fire projectiles into it, and every projectile that lands stays embedded — which means each successful shot reduces the space available for the next one, and the level is cleared only if all of them fit. That self-narrowing structure produces the specific tension the game is built for. The first shots are easy and nearly meaningless; the last one has to thread a gap barely wider than the projectile, in a target that is still rotating, with everything you have already fired in the way. Rotation speed and direction change between levels, and some reverse mid-level, which removes the option of settling into a rhythm. Levels take seconds and restarting is immediate, which this difficulty requires. There is nothing else in the game: no upgrades, no progression beyond the level counter, no score. That is appropriate — the idea is complete and adding to it would dilute the nerve test at its centre. It plays with one input, works identically on a phone and a keyboard, and runs on anything.
