Use the mouse to point your pogo stick. Press S to configure settings. The only current setting allows you to make the pogo stick point towards the mouse only if the mouse button is pressed. Don't hit enemies or you'll take damage (seen on the right corner). Don't hit the edge or you'll die. Every second you get a point (seen on the top left corner). Next to that, there's the highscore and the name of the current highscore holder. The game gets faster as it goes, so you have to be fast. It's harder than it looks.
