This game really made me want to keep going once I got into it :-)
The whole aesthetic was very nice and fit the game well. I think the game could really benefit from a map of some sort. I noticed a lot of dead end corridors, it would probably be more interesting for them to end in rooms.
A few bugs you might be interested in: At a few times enemies had gotten "stuck" in furniture, where I couldn't attack them and they didn't attack or chase me. If you go downstairs and re-enter a level, it is possible to enter on the same tile as an enemy. Also at one point the caps at the ends of a wall didn't generate (see below).
A fun game overall but the beginning felt slow so I wasn't eager to jump right back into it after dying deeper in the dungeon. If you decide to continue development then I think some added variety would easily solve this and elevate the game.
