Sorry for the terribly late reply. I don't have an official forum for the game, but most of the discussion happens on the facebook page.

Also I haven't updated much in the past few weeks. I got a little burnt out from the third dungeon, but I've finally planned the mechanics and began designing the fourth and final dungeon.
Obviously there's a bit of polish I still want to add: More side areas, more quests, a working options screen, and so on... but an official release on the store is finally in-sight!
