Disappointing. I don't generally mind paying for games that I think I'll enjoy, but I devs need to be upfront about this. The gameplay is solid, but this game is a demo. *Spoilers* After the first boss fight, you unlock another island which can't be accessed unless you pay $6.99 or watch 20+ ads (with ads for every dungeon run). Up until this point, there is no indication that this is a limitation. Dev, be transparent and upfront that this is a demo and additional content must be purchased.
