Amusing
While the sound got a tad annoying for me, the game was quite entertaining. Being able to play as some of the well known Newgrounds characters, while beating up on the others, was quite fun to say the least. The only problem I found, was that you could pull off jump attacks, over and over, and still win. However, the creators are not really at fault. Infact, they even made some of the characters limited in their jump attack capabilities.
This game is a bit like Super Smash Brothers in the way you fight on a single map against opponents. Ah, it was good to kick some ass. ^^ Good job guys.
