I was really confused about the chess piece icon, that didn't seem to do anything.
Also this may be a bug, but it seems like dice never fell on the edges of the board, so you could just cheese the game mostly by just hugging edges. A timer and score to show how long you've been surviving for would be nice for replayability. Maybe an indicator of what dice is coming up or that the game is getting harder. I'm just throwing out ideas here!
