Use A D/Left Right to move and Space/W/Up to jump. To ground pound, press S/Ctrl/Down. You can wall cling by holding a directional key into a wall. You can 'swing' on logs by repeatedly jumping into them. If you touch enough hearts, you can unlock the challenge mode! If you unlock challenge mode just go into the game ad move the character to the beginning of it, I can't be bothered to try and code checkpoints again If you're stuck or want to try again, press "R" to reset
