Several games, none of which is more than 4 seconds long. Most of it's simple stuff, like branding a cow, chainsawing a zombie, or blowing up the world. And all games are played using only the arrow keys and spacebar. There are more than 50 games in total, and you get to choose which ones to play. The rules are often vague, so pay close attention when the rules are displayed (they disappear quickly sometimes).
Controls: Arrow keys and spacebar
