I like this idea a lot! I like how the downgrade system forces you to either completely lose a stat for a round, or play with 2 significantly nerfed ones, before you get the buff of a negative stat, and then you have to make that decision again when you max out (min out?) the negative stat. I wish there was more to play so it could last longer, and you could go from being completely feeble with 0 stats all the way to busted powerful with all negative stats. It'd also be interesting to play with other abilities that become more powerful with negative stats, like being able to move extremely quickly but all of your controls are reversed (negative movement speed), and so on.
Also I had no audio? I don't know if that's a bug or if there simply is none
