The sprites and and the bouncy walk animation are super cute! However, I'd recommend explaining in the instructions how points are scored. I played a few runs, collected every die I found, got past the first boss with 0 points, and almost moved on to the next game before I realized from one of the screenshots that you're supposed to bring the dice back to the chute in the first room, where they can be rolled to add to your score.
I did another run after that and got 34 points, so for other players: there's your score to beat! My run seems to have been cut short, though - I reached the "End of run" screen with 3:42 left while attempting to go through a door in the second world that didn't seem to work. I only had 20 HP left, so maybe I got hit by something through the door?
