I liked your take on the theme. But there are some issues, which did't let me to have fun:
- Difficulty. The game is too hard from the beginning. I was attacked by 3 skeletons and got destroyed in seconds;
- The cooldown for the player's attack is too long;
- It would be great if the game had some explanation / tutorial on how to play it correctly, since the mechanics are complex.
Anyway, well done!
