Sprunki Jump

An endless vertical jumper whose obstacles are placed on the soundtrack's beat. That single decision changes the game from a reaction test into a rhythm exercise: the next safe moment arrives on the music, and a player who listens is working from a cue that arrives slightly before the visual one. The climb escalates by tightening the spacing rather than by speeding up the track, so the rhythm stays learnable while the margin around it shrinks. That keeps the failure honest — a missed jump is a press out of time, not a hazard that appeared too quickly — and it means improvement comes from internalising the beat rather than from reacting faster. Long runs feel calm rather than frantic, which is unusual for the format. Runs last a minute or two, restarting is one press, and height is the score. Sound is effectively required; muted, the game is considerably harder and much less interesting. It plays with one input on a phone or keyboard and runs on anything. A small game built around one good idea, executed without clutter. There is nothing else in it — no unlocks, no modes, no progression beyond the height number — and the single idea is strong enough that adding any of those would have diluted it. A thirty-second game to open between other things.
