Cute, though the theme feels a little slapped on to be honest.
I think it would more sense to capture the mouse when you click the puck. The way it is now, it makes a huge difference if I play in windowed mode versus fullscreen mode since I can land much more powerful shots in windowed mode.
Not entirely sure why you went for a puck and then gave it so much friction. I feel like a puck should be more slidy? Maybe that’s because you usuall use it on ice, though.
I quite like the background artwork!
Overall, a pretty neat entry. Nothing groundbreaking, but I enjoyed it enough to play through the entire thing. Well done!
