Nice concept but the game feels wonky.
The skeletons sometimes take multiple hits to kill and do not have a health bar, and then the red ogres are introduced, which do take multiple hits and do have a clear health bar.
Level design is implemented without purpose, rooms exist just for the purpose of making the game longer, and not contribute to the gameplay at all.
The dragon boss fight is neat, but the entire game you defeat enemies by touching them, and then that's not what you're supposed to do against the dragon.
Still, good job on your game!
