This is a really cool concept.
The dungeons look okay, but the sprites are a bit rough.
You should be able to use items by double clicking on them, and maybe some quickaccess slots would be useful especially if you decide to add combat utilities like throwing knives and such.
Combat is a bit meh, you fight all enemies is kind of the same, you backpedal out of their attack and then take your swing, it could use some variety.
For example the goblin and other unarmored creatures could get stunned when damaged so you could be more aggressive against them.
Map generation seemed fine, but sometimes enemies that spawn in a corridor get stuck:
I can see the concept working well, especially when spells and better gear get throw into the mix, I hope to play more of this.
