Very cool design! I could only do the WebGL version so there were the given issues, but that's to be expected and did great considering. Nice flow of combat, and the weapon options were satisfying. At times some level design details felt a little unexciting the longer it went, but within a month this was a great construction. As far as art design goes, it felt a little odd having some things very high detail but then others very low poly. I like both, but having them side by side just made things feel a bit cut-and-pasted. All in all awesome job though, kudos!
