the under water zone was neat! still a little bare (probably cause it's still w.i.p), but it will add more zones, monsters, and other stuff that can spice up the story/adventure. my only minor grievance was the load time on the zone, as when entering the new area or exiting the player screen while in the new area the game would buffer for a while to load the zone.
but yeah, overall i can't wait to see what else you'll do with the new zone type
P.S. good luck and have fun at your event
