You really don't want your player to catch a break, do you?

Seriously, that's a good arcade concept but you might want to give us a few seconds of calm at the start to get a grip on the controls. 

Speaking of those, I feel like there's a bit too many possiblities for such a fast-paced game; maybe you should choose either melee or shoot and stick to it (or give the player the choice at the beggining?), cause I don't feel like it's possilbe to do both at the same time when running for your life. Or maybe I just suck at it, not impossible.

But there's definitely juice and a good feel in your game, so great job!

Nice concept! I couldn't play for long though as the camera movement was a bit over the top and made me a bit nauseated sadly.
