I like this! It feels and play like an early GB game for sure with the floaty jumps, the graphics and the simple quests.
I find the enemy hitbox a bit wide (or the character one), it seemed like sometimes, my sprite wasn't touching an enemy and I died. I assume the hitbox is wider than the sprite. Other than that, maybe the game could have hit points like hearts. 1 hit kill is pretty rough!
Great one! I think the art and the music are great.
Good job on your submission!
