Menu text is REALLY hard to read, no contrast.
I don't understand how the bots work, like which ones will explode when they get touched and which ones don't. (unless it is just a bug and they are only supposed to explode when they fall off stuff)
The camera movement is odd, because it will mess with your controls, I would rather have a static follow camera that doesn't have rts-style delay and follow target, unless that's what you're going for.
Checkpoints feel sparse and I think there should be a way to get more lives if you collect the stars, which gives a reason to collect stars and also makes it not so much a pain to restart.
Overall as a monkeyball/gmod tower fan it's pretty good, keep up the good work. I like the UI, sound design, map design, and overall art/aesthetics.
