A very good concept once you learn the core mechanic, but it sometimes feels a little unfair (I played one game where all my first options were dead ends and couldn't get out of the starting block). It's simple and fun when you get the right tiles.
The overall style is also cute!
PS: I found a small bug where sometimes you can move on top of a blank tile if you hover the mouse on one of the options and try to move in that direction. I got a TON of reroll biscuits this way.
