Great concept! It would be cool to lock a die for use on future turns. And it would be nice to see which dice types are left in my bag. My only gripe is constantly needing to hit the "end turn" button while waiting for a 1 in order to use the exit. That could be solved with something like a die-lock feature, a die that rolls 1, 2, 3 only, or a die that rolls "odd" or "even" and the player choose the number. Lots of room for expansion, which is a sign of a great game
