I appreciate the foundation of what you've put together! You've definitely got the basis of a game here, and I feel like without too much embellishment at all you could have an overall gameplay loop going.
I appreciate the fact that the game does have a lil' ending already, and with the systems you've built I could totally see our hero going on all sorts of hack-and-slash adventures, potentially more diverse attack mechanics like different keys to press like quicktime events, or specific combos, etc.
Obviously as you stated the game is heavily incomplete, but as a result of this I can see a lot of potential for this project depending on how much you want to put into it!
Keep workin' on it and keep learning!
