wow, nice! I'd be interested in using it if you want more testers! Since you come from the industry maybe you should look at a console version? Small world I used to live in Orange back in 2000 and worked for Sega GameWorks for a number of years while they were trying to grow. Helped out the Irvine and Ontario locations as well as Vegas and Seattle.
