How to play
  • Move with the arrow keys or A and D. Jump with Space, W, or the up arrow. On a phone or tablet, use the buttons on screen.
  • Hold jump to go higher. Tap it for a little hop.
  • Jump on a chompy's head to bonk it. Touching one from the side costs a heart.
  • Spiky balls can't be bonked. Jump over them.
  • Hit a crate from below to break it and get a cookie. Red mushrooms bounce you way up high.
  • Touch a lantern post to save your spot. Falling in water or a hole sends you back to it.
  • P pauses. M turns the sound on or off.
