My game is based on the same core idea :D Nice game, interesting levels & button mechanics, lovely visual style. The dice moves a bit too slow for me, maybe the speed could be adjusted depending on how fast the player does press the keys. Sometimes the number above a tile is very close to another glowing tile and it is a bit hard to see what the number is (added a screenshot). Anyways, fun game, nice job! Consider trying my game if you wish.
