I loved the graphics and the idea to build the adventure as you go is genius!
I felt like the combat mechanic was a bit odd because I didn't really have an incentive to fight, I can get loot by getting treasures and avoiding combat so I actually don't really need loot. Maybe making the monsters drop the tiles instead of loot would force me to fight them to progress while making loot interesting to be able to fight the monsters, I don't know...
I have mixed feeling about this one because it is good (regardless of the bugs) but there is a tiny thing missing to tie everything together and make it amazing.
Looking forward to see if you keep developing it because I'd love to see where it goes :-)
