Nasty Surprise

Nasty Surprise is a platformer that is angry at you. The rule is simple: start on the left, reach the green door on the right. The problem is that the level does not play fair. The floor under your foot vanishes and drops you into nothing, spikes shoot out of the ground, a toothed press slams down from the ceiling, a spinning saw blade falls and rolls at you, a wall pops up in your way, and the door simply walks off somewhere else when it gets bored. Each of the fifty hand-built levels teaches you a new piece of treachery by stabbing you in the back with it first, then mixes everything together. No jumpscares, no screaming faces, no horror — just traps and timing. Dying is free: you are back on your feet in half a second and it only costs you points. Scoring rewards fast, clean runs, your progress is saved so you can pick up where you left off, with best-score tracking and a local leaderboard. Arrow keys and space on desktop; on phones an analog joystick that appears wherever your thumb lands, and a tap to jump. No internet, no download needed.
