I really like the environment and the atmosphere it creates. I also like the story and how storytelling is incorporated into the environment. Very fun!
I think to make this game even better, you may consider showing the cooldown of the attack, and adding more variety to the combat. I already like the storytelling, but I think you can push even harder to incorporate a richer story.
Overall, while the game feels a bit unpolished, your ideas shine through. You should be very proud of what you've accomplished, and continue to work on it! Nice attempt!
