Your presentation is great. The art style and sounds are amazing. I think this game has potential to be expanded on and see success. Really, it's good! That's why I feel obligated to give some criticism.
I think the fundamentals could use a bit more work. The ball moves too quickly and randomly for the slow movement of the paddle. Maybe if the paddle movement was handled my the mouse instead? It would let you open up the skill ceiling much further. It would also open up the skill ceiling if you let the paddle velocity influence the ball's direction when it bounces. I also struggled with the UI and how to navigate through it, maybe some on-screen labels would help with that.
Otherwise, one of the better games I've played in the game jam. Really good work, bravo!
