block chain
arrow keys: move around
- don't run into the chain you leave behind!
- however, you can cross over straight chain segments
- blocks with horizontal lines can be passed through horizontally
- blocks with vertical lines can be passed through vertically
- each block contains a certain number of coins, represented by the number on its face
- chaining blocks together will make blocks send their coins forward along the chain
- when the last block in the chain is empty, it will disappear and earn you one point
