I love this artstyle for the game. Reminds me a bit of Twin Peaks. I would love to learn more about the world and seeing a close up on the main character in the game. They have a very interesting design.
The boss is also a really cool design, I think all of the designs are really neat.
I do think that it was a bit easy fighting enemies as I could just kite them around the map.
A great addition would be more levels and maybe some bits of story laying around to explain a bit of what's going on. Also some more hit reactions would also be a great addition.
Love what you got here and keep up the great work!
