Action Packed

I quite enjoyed this and love the direction you went with the theme! Great art style and music. They both mesh so damn well together. Really great job there. 

Art, and music wise, ya nailed it. 

Gameplay wise, I feel like there's a lot more polish to be done. 

For one thing, the fact that weapons don't seem perishable, means I just got one hammer and spammed it forever. I couldn't see much reason to use any other weapon in my 3 (admittedly short) playthroughs.  Hammer does the most damage, without wasting mana. That seems to be the optimal strategy.

Give me a reason to use the other weapons. Like the bow and arrow does extra damage against flying enemies. Hammers are great against small enemies, but not against big ones with too much armour. Knifes could be great againsy big monsters because they pierce armour but crap against everything else. Etc... Just examples, just think along those lines. 

I think it would be more fun if there was more stuff that happened in the dungeon as well, like meeting a merchant to buy more/new items, a random npc that sasy something funny or have a tiny riddle or minigame, a small camp to rest. Break the monotony of constant battles. 

Finally, could be cool to choose which dungeon to go to before you go on your adventure. That way, difficulty can scale, and there could be more strategy on what items you choose based on what monsters are more common in each dungeon. 

Overall, I had fun, and love the direction you went with, and hope you keep working on this and make more games in the future! :D
