Why hasn't anyone done this yet?

It's a boxing level.
hope you guys enjoy it. And i am desperate for new ideas for this level. since the idea is pretty simple

PS: its using a custom character!

Okay I haven't played the level yet but...

I would set the room to '_dojo' (sword only) and then make sword animations into like an uppercut type animation for a character wearing boxing gloves (don't actually give them a sword).
Also it would be cool to have a crowd in like a small stadium around the ring (see: the 'Gladiator' level).
Throw in a bunch of minotaurs! Maybe consider adding progressively more difficult rings/stadiums (with bigger crowds)

Mind if i 'adapt' your ideas? The boxing stadium with the additions from eamonn? :)
