A phsyics-based game of "Hot Potato" is a pretty interesting idea!
I do think the game could have benefitted from a tiny bit of in-game explanation. Like at first I didn't realise the red guy was my opponent, I thought I was trying to kill/defuse/get rid of the bomb in some way.
Art style is very unique, and I think that the SFX are pretty good (although a shorter more punchy throwing sound might have been better, so that it didn't 'lag' behind the throw so much).
I also think the opponent would have benefitted from being more agile, at the moment it's pretty easy to just give it the bomb and wait it out.
Good job though, keep up the great work!
