Okay ummm.... theres a lot to say, but ill keep it short and sweet(i'll try)
I loved the automatic doors, great Idea!
I dont know about others but the enemies were way too easy, most of the time i was just standing in one place and shooting.
I liked the swaying when you were running, it looked a bit natural
The boss was pretty good
Well overall its pretty good, being a game develpoer myself i can tell its pretty good!
