Fun little game. The difficulty curve felt appropriately challenging, and there was a good amount of strategy in terms of movement around the levels. If there's one area that could be improved, I'd say the player should, in some way, have a little bit of control over the die roll. There is a frequent scenario in which the player is missing a single number and must spam rolls for a while to get it. Since movement is already the main thing the player controls, maybe the player's location within the level could influence the die roll? For instance, if you know the number you need is to the right of the current face on the die, rolling while standing on the right side of the level could influence the die to roll more "right-wardly."
