Fun and fast!
This is a pretty cool and simple game. I could see this becoming a quick versus game if you have some time around the office.
Some things I think that could be addressed if you cared about balance as a fighting game are as follows. Powerhouse heavy hitters like Mindchamber could easily knock off an opponent from the middle of the ring if he's unable to move. Kinda defeats the purpose of the faster lighter dudes no? And with the speed freaks like liljim, I found a good way to deal damage was to push them off the ring (for some reason Luis and a few others actually caused me to lose ground when they got stunned and I tried to push them). I think a reasonable compromise here is to make it so characters like Mindchamber can knock you close to the edge from the middle of the arena, and make falling off the ring do more damage than it already does.
And for the people complaining about the lack of a mute button, I'm finding I'm agreeing with them. Don't get me wrong, I think the music as a whole is good for this game. But it's the opening segment that is NOT okay, and the music restarts everytime someone dies or something. I was half tempted to try to counter it with Nyan cat.
Overall, fair execution. And thank you for the nice speedy response about the Stamper glitch. Respect++;
