I think this was a fun game!I really like how the music doesn't get overbearing (which can easily happen in games like these).
Some notes of what I think can be added to make the game pop some more:
Add a bit more of an impact to the actions. It's fun to shoot and attack currently, but I think it could feel even better if there is some impact when we hit the enemies, which can be a sound effect, or particle effects, or similar.
This is more for further iteration, but it could be nice to add skills into the game, so that you're not just pressing one button while you're attacking, and instead have more varied movement options. I think the dash is a good start, but could be cool to have different attacks for example. They could even be added as loot!
Overall though, I had a fun time with your game, and also liked discovering the loot as I played. I thought it was really cool how the loot was themed to reinforce the theme of the game.
