Key Jumper is a slime parkour run across a giant keyboard. Hop from keycap to keycap, clear the gaps between the keyboards, dodge the red keys that drop away and bounce on the green ones, all the way to the big Enter key. If you have played Slime Keyboard Escape or a keyboard obby, you know the idea.

Keyboard parkour is one of this year's surprise hits. Slime Keyboard Escape sits near the very top of the most played games on Poki, Keyboard Escape: Speed Parkour climbed into the charts of more than twenty countries in a few days, and speed-keyboard obbies keep arriving on the new-games lists. Key Jumper brings the same giant keys to your browser as a level-by-level run you can play free on any device.

Every level is a course of floating keyboards running away from you. Plain white keys sink under the slime with a satisfying click. Holes in a keyboard make you pick a line; stepping stones climb up; long single-key bridges test your aim. Red keys shake the moment you land and drop a second later, so keep moving. Green keys are springs that throw you high across a wide gap, and blue keys slide from side to side over the void. Long space bars are checkpoints: fall off and you start again from the last one you reached.

The levels grow longer and bring in new key types one by one, and every course is built so that each gap can be cleared with a jump from the edge — there is always a way. Stars are for a clean run: finish without falling for three. Stuck on a nasty stretch? The skip button takes you straight to the next space bar; you start with one, they carry over, and a short video brings more.

Key Jumper runs on desktop, phone and tablet. On a phone, drag anywhere to steer and tap the big arrow to jump; on a computer use the arrow keys or WASD and Space. Your level, stars and skips are saved in the browser, and the leaderboard ranks the furthest jumpers. New to obbies? The first course has no traps at all, and the hand shows you how to steer and when to jump.
