Nice game, and good limitation of the arrows. Personally I prefer dungeons in games that are connected to fewer rooms, (1 or 2). In this game it feels like there are a bunch of "pointless" rooms, that could be combined to one. Also some more variations in the dngeons would b enice. I can see you added some small details here and there, but I think more is needed. Perhaps you could also have different envoirments for each "dungeon level".
Otherwise nice game!
