Cool idea! The intro of you falling into the well and then grabbing the sword is well done. I think the player character could do with having a higher walking speed. The attack area for the moving enemies seems very specific - I would be swinging my sword right up against a beetle and nothing happened unless I made the character face it directly - I think when wielding a sword it'd be nice to account for a larger area of attack! Kudos on creating a dungeon with several rooms, different enemies and locked door elements in a short amount of time! I would also maybe increase the player health a tiny bit since as it is you get hit once and have to start over again :)
