Very cool little game! My one complain is that it pretty much felt like luck rather than strategy on if you did well or not, because of the randomness of the dice rolling mechanic I found myself usually getting stuff that wouldn't really contribute to my score at all, maybe weighting the dice to what the player needs would help that a little bit. One bug that noticed is that if you have a die selected and you try to select a different one it will use up the first one, not sure if it was intentional but it's a bit annoying.
Overall, this game is very nice with it's niche pixel art sprites and music, just needs some refining in terms of the gameplay.
