You entered the cave seeking fortune. Now, a monster has imprisoned your heart. You must journey through the cave to your heartbeat and find a way to take the monster down. Use the Arrow Keys to move, and down to crouch. Use the Up Arrow Key to jump, but you can only jump when your heart beats. Use the Z key to attack, but you can only attack when your heart beats. In the final level, you have to go to the top of the Colossus without touching it and stab it in the eye.
Thanks to @griffpatch for a scrolling platformer tutorial. Inspired by Crypt of the NecroDancer.
