Right now, Mr. Brennan appears to be playing up the diversity of the cast and audience while offering little info on what the game actually is other than "real-time cooperative". The old Casual Quest was a session-based, top-down brawler sort of like Gauntlet, but with a single screen map and class evolution. The alpha of the browser version I jumped in ages ago had larger maps. Other than that, I'm not sure, but there should be a new video demo next week.
The original Casual Quest took first place in a paid game dev competition while my Fused Finale took second. My broke ass is pretending that's a donation. ;)
