Very well polished game! Loved the graphics and the gameplay was absolutely awesome, definitely going to read the devlog, I have no clue how you managed those ball mechanics!
I struggled to find any feedback in all honesty, it's really well polished, but here's what I've got:
- A pause menu / mode would be quite helpful since the rounds are relatively long
- When you return to the menu you don't really need to see the "PONG" drop in again, and although you can skip it, it's a tad annoying... Although that's more personal opinion
- Maybe changing colour palette every round would be cool?
But yes, this game is very well polished for a game jam entry (making it really hard to find feedback!!), fantastic job!
I recorded a quick video, in case you want to see how bad I am at tennis XD
