Cool little game! You did a good job of picking art that fit the story and vibe of your project; it really feels quite cohesive.
A map would be a great addition if you're going to keep working on this. That was probably the thing I most found myself wanting while playing.
I also found the combat a bit weird, mainly because of how close you needed to be in order for the weapon to work. I can't say it didn't feel good (it felt okay, especially after playing for a while), but it definitely felt weird to me and took a bit of getting used to.
I think overall the game is pretty cool! Good work!
