The visuals of the game are appealing, the theme and special object definitely there. A platformer is very basic, but the bullets you have to defend against with your shovel make it more interesting. As others have already pointed out, the music itself isn't bad but that it is so short and always repeating makes it hard to endure. For the bullets, if you were to develop it further in the future, I'd suggest make them bounce off the shovel in the opposing direction instead of them just disappearing, that would give the player a bit more feedback for the right shovel direction to defend against the bullets. But for the limited time frame of the jam, well done!
