Let me start off by saying, this is an incredible entry, and it's super juicy. I think you did hit it out of the park in terms of polish, graphics, animations, sounds, little details like screenshake etc. Having said that, I think in terms of gameplay, some things can be tweaked to make this experience a 'hole' lot better ;-)

I'd recommend making the playing field a circular cutting board, instead of a square one where the ball often gets stuck in the corners. Maybe it's also advicable to make sure the ball can't even reach the outer edge, so the players can always reach it. Second thing is that I think the movement of the players can be a lot faster, especially for a CO-OP game where you're kind of trying to beat each other. A great addition to co-op would also be the ability to tackle each other! I think that'd be hilarious. I played on a PS4 controller, and I think the bindings didn't correspond to those you wrote on screen, so maybe look into that? Another tip would be to make the text above the player always face the camera, so it's not facing the wrong (and illegible) way once you pick up the ball.

I did really love the interaction with objects, maybe make them have a bigger impact on gameplay, like a huge knife coming from above to actually slice up tomatoes or whatever, and you'd have to dodge the knife etc. I did really like this game, and I think that with some changes you could actually sell this in something like a co-op party pack! Great job dude and I wish you the best of luck on your journey to polish this game!
