This was a lot of fun!I My team hadn't once thought of the jam idea of a computer virus! an it was creative to add the physical microscopic look of a virus to portray that. That sprite/icon is what got me to click in the first place. All the load outs/classes  had me playing a third time around just to see what each of those were like. I loved seeing the popups out of the corner of focus and chuckling at the clever text while I was playing haha. I also liked the different enemies and how they forced you to constantly move. A Trojan Horse would fit perfectly in the cast of enemies ;) The thing I found myself wishing for was some way to gain health back or clear the map when the spider-like infections/enemies were too far away and hard to focus on. The mouse/target icon was also very hard to see when you're in the thick of the action. Maybe a "back up" state or some map clearing mechanic that you could trigger would help ease the stress and keep the gameplay going for longer periods as well. Overall though, I had fun with this and I love the idea of it being a computer virus that's spreading! 
Applaud your creativity and hope to see more from you :)

Pretty fun. Humorous. The secondary skills don't seem quite effective for how much charge they require. Also bullets seem to skip over enemies with small hitboxes. Eventually the popups are unavoidable, maybe have some way to close them? Anyway nice work.

Its a really cool and creative idea! Wish I could have an indication of the stats attached to the player instead of the corner.. its harder to look with all the mayhem :D
