Dang this is a cool project to have cranked out in such a short time. Well done! 

I loved the music. It totally fits the gameplay and helps keep the pace of the game feel quick and snappy. 

I think the controls are the weakest here. It feels just a little too loose. Combined with the low fidelity 3D make it a bit tough to judge where the ball is sometimes. It's especially apparent on the serve. Or at least that's where I embarrassed myself the most by just.... missing a stationary object lol. But this was a jam game. That level of polish isn't expected.

Super well done on this! Congrats!
