Very creative game! I love the menu design and the fact that the number of dots on the die updates whenever you damage it! Love the Dani-style post processing XD. I myself am an admirer of Dani.
A little constructive feedback: as others have already mentioned, the pop-up disrupts the flow of the game. If you do really need it, would be better if you added a PRESS ANY KEY TO CONTINUE instead of having the player drag their mouse to "CONTINUE" to close the pop-up.
Next would be to add a cooldown between the shots. I have an auto-clicker built into my mouse(I don't even know why there's one, just came with the mouse), and based on my experience, I'd recommend adding a cooldown so as to not make it too easy for those who have an insane CPS XD.
Overall very creative game, beautiful visuals and great take on the theme.
