The Super Smash Cats Brawl that I never knew I wanted!
The effects are great, from the sound & music, to the parallax and post-processing, and the crunchy effects, it's easy to see a lot of love went into this. However, I'd argue it's not a fair fight, as the AI tends to just gang up on the player. If they were to attack one another, the gameplay would be more interesting by an order of magnitude. I also recommend two simple moves (even if just for the player): right click to block, and left-click whilst airborne to ground-pound.
Nevertheless, a rather impressive brawler for a game jam. Well done, and good luck! :D
