Simple game. I like the idea, but I don’t think it was executed in the best way. Maybe if the aiming reticle for the ball rotated more slowly, you’d feel like you have more control over how the ball moves.
The sounds are nice, and the visuals are simple but sufficient.
The “Next level” button didn’t work for me.
Overall, a nice project. Since this was your first game jam, the next ones will only get better. Looking forward to them!
