The level looks fair until it decides to kill you.

how to play

You cross 20 levels, and each one ends when you touch the green door. The scenery is flat geometry on a dark background: light is floor, red kills, purple only gives way to the dash. Up top sit the level name, the timer with your record, and a skull counting deaths.

On the keyboard, arrows or A and D run, SPACE or Z jumps, SHIFT or X dashes, down arrow slides, R restarts and ESC pauses. On phones the stick is born wherever your thumb lands, on the left; JUMP and DASH sit on the right, and the stick aims the dash.

The dash is a single charge. It comes back when you land, when you touch a wall in mid-air and on the wall jump itself; purple walls do not recharge it. Spikes, saws, lasers and crushers kill on contact, and getting squashed by a moving block kills too. Dying rearms the whole level.

Levels open in order: clearing one unlocks the next, and your best time, lowest death count and progress are saved in the browser. Time earns a medal against the level par: gold up to par, silver up to 1.4 times par, bronze up to double.

tips

Sliding needs speed: standing still, pressing down does nothing. While running, the slide adds a push and shrinks you to half height.

Fake floor vanishes 0.16 seconds after you step on it; the orange block cracks and takes half a second to fall.

The hurtbox is smaller than your body: you can graze a spike and live.

Dying does not reset the timer or the death counter: only R restarts the attempt from zero.

The crusher pulls back a moment before it drops, and that pullback is your warning.
