I really like the concept and the art style! The game has a lot of charm.
The only thing I struggled with was the combat. I wasn't really sure how it worked. I sat there spamming the space bar, and even when my bar was full and the enemy's was almost empty, I still couldn't seem to land a hit most of the time. I'm not sure if I was missing something, but it made the combat a bit confusing for me.
Other than that, I think it's a really cool idea. Nice job!
