Just one thing...
Graphics were perfect for this type of game, style was great with each character ahvign two "weaknesses" and strengths and being good at air or ground or whatever. sound was good with piconjo and s'asshole both saying alot of stuff while they fought and each stage having a different somg, violence is a given since everyone who loses dies, interactivity is a 10 cause this is a game afterall, humour is good like how salad fingers wants to befriend all his opponents and then fights them, and that makes the overall a 9.9, which is rounded to 10.

I beat all the storymodes, and the challenges, and bought everything. Is there anything else left in the game? I feel kinda wierd having beaten everything in the game and having nothing to show for it.. Is there like a "congratz, you beat everything" or "omfg secret boss time" thing in this? Like put a totally original overpowered character as a final boss of some sort in a hidden area where you can never go without facing him. If you're making a sequel you should put something like that in there. Other than that this game was great.
Oh yeah, and i took off a point for sound cause some of the songs get annoying, such as the menu song.
