This is quite enjoyable for just a demo, but I have some personal small problems. It's more of just pet peeves more than anything.
-The lack of being able to aim with my mouse was kinda weird. Feel like it would be a bit more enjoyable if I were able to do so.
-I feel like the powerups should have some kind of indicator when it is close to ending. I say this as I generally got closer with the shotgun and I tried to shoot the Soldier with the shooty shooty bang bang with my shotgun. However, it literally ended right before I got to shoot him and promptly got hit since I expected him to be dead. I could just be bad but just a suggestion.
-If I'm on the very top and I get hit, I can't see how much HP I have since its off screen. 
-More often than not I kept getting hit by enemies coming out literally right behind me, perhaps make a small indicator when the door is about to open/when the enemies are about to come out. It shouldn't be too long but just enough to let us register that they are coming and maneuver our way at least get away so we don't get hit instantly.
Hopefully I don't come out as nitpicking or something. I honestly had a lot of fun for such a short experience and simple game. You don't HAVE to do anything I say, just feedback really. Sorry for the longer than average read I didn't know how to shorten it.
