Unlock all the locks! Use the Arrow Keys or WASD to move. Push a black key or heart to slide it. It will keep moving until it runs into something. Keys need to collide with the yellow locks. Hearts need to collide with the red locks. When a lock is unlocked, you'll get an extra key or heart that you can use.

Later in the game, you will encounter gray blocks that you can only move one space. Blocks that have horizontal arrows will move on a row, and blocks that have vertical arrows will move on a column. Use these to your advantage to help you push each key and heart into their destined lock!

If you or one of your keys get stuck, press R to restart the level.
