fun to watch, though a bit short
The characters may be just blobs, but at least they've got a fair sense of squash and stretch.
The arenas are a bit sloppy, but that's not too terrible. Just something to work on to further improve it.
What I reckon would really help take it to another level and not be too hard is if the commentary was vocalised. If you've got a good voice, shout it all into a mic. Or get someone from the VoiceActingClub to do it, like a proper presenter. That'd be cool.
What made this though, is the idea. It's been done before, but I suppose it's something with serious lasting appeal.

Anyway, it was fun to watch, though a bit short.
