A small endless runner built for this site. Jump the crates, grab the gems, and see how far you get before the speed catches up with you.

Space, arrow up, or tap the screen to jump

How to play

• Space, arrow up, W, or a tap on the screen jumps.
• Crates end the run. Gems are worth 25 points each.
• The run speeds up the longer you survive. Your best score is kept in this browser.

How it works

The game is simulated on a 320x180 pixel grid and drawn into the same offscreen surface the CRT shader grades, so the curvature, scanlines and phosphor bloom you see are applied to live gameplay rather than a recording.
