Very solid in it's execution. good job. I like the art style and animations. The sound effects are also very nice.
I noticed that the soundtrack switches between electric guitar with distortion to acoustic guitar, depending whether or not you are close to an enemy. Very nicely done!
-But I would improve the music for sure, because it sounds very empty, and the melody is not very consistent.
The map design also has a lot of room for improvement imo. There are a few parts that deceivingly enough urge me to go in a certain direction but then I can't.
But overall good job, keep it up!
