I beat it!
Cool take on a diablo-like game. Had some pacing issues in the beginning - I think I was level 4 when I beat the first boss and that took forever, then beating the boss shot me up to 16. The second dungeon was a cakewalk and I finished it first try. Then the third dungeon was very hard, and level scaling made it so I had to grind a bit to power up. I beat it at level 30 by stocking up on potions and tanking the dragon.
All in all a fun grindy game when the balance is right, which for me was definitely dungeon 3.
Did you do the art and music? It looked really good!
