Okay, I played Razz Arena. What I can say:
-The grass outside the castle is FLAT. Plain flat. Bump it a little.
-Some names are wrong. Rename Bouncher to Bouncer (you use inproper spelling, you!) or even better BBT Bouncer). Rename Shotgun to Pepperspray, and Rocket Launcher to Seeker.
-The voices suck. And they have bad words. May I and JSZ Spaz give you voice samples for Jazz and Spaz? Just give me a list of voice strings needed.
-Use more wall textures than just the big block. The level has very poor eyecandy.
-In JJ2 all weapons are in Blaster, but I think this one isn't good in FPP. I can design new weapon looks for you.
