I gave the level a short try-out, and it was fun!
I'm afraid I was restricted to the lobby (so take anything I say about the actual "arena" witha grain of salt :p ), but from what I saw it was a decent level. Here are some comments/suggestions:
- I really like how you implemented the weapons room, so that players could see the weapons through the glass from up top while the host was down below slecting. Really unique idea, and very efficient with space.
- The arena looked good (from what I could see through the windows, I was too lazy to open up the arena in JED), but the water seemed rather lifeless. Perhaps get an animated mat or somethng, just make the water seem more alive.
- Were those cobwebs I saw from the tower? They looked pretty cool, but perhaps a little out of place.
- I like the banners. A lot. Keep them.
So, IMO, the main tihng that needs changing is the lighting. The level will look so much better with some shadows. Great work though thus far, I hope you enter this in the competition.
