I jumps. II headbutts. On a keyboard, Space and X.
HOW TO PLAY
Dinosaurs run at you. Jump over them, land on them or meet them with your forehead. Ships fly low, so mind your jumps.
Meat is worth 50 points. Every third piece makes you shine, and nothing can hurt you while you shine. Stars are worth 200.
You have three hearts. Tap the left half of the screen to jump and the right half to headbutt.
Cave Run is our own little game, with our own caveman. It is a thank you to the platformers of 1989.
