Pretty cool dungeon crawler!
The feeling was really Game Boy-ish, you did a great job on capturing the essence of the jam. I loved the weapons, they were satisfying to use. Same with the overall art style.
My only issue is that the character seems to be centered on the overall viewport of the game and because of the GUI, we're shifted a bit to the top of the gameplay section. We have a hard time seeing enemies coming from the top of the screen.
Good job on your submission!
