I like the idea of the game, as well as the movement animation you created for the dice. however there were quite a few bugs inside the game. For one, sometimes the game would crash for some reason when i got a point. Secondly, i think using dots instead of numbers would make the game much more refined, however i understand that you may not have had enough time to do that.
I also suggest you add a few more features here and there, to make getting the correct number more different each time. For example, you could have it such that certain directional keys would be limited, either from the start of the level or if the player accdientally picks up an object, or maybe allow the player to jump in order to spin their dice faster
I'd say keep going and good luck on your future games!
