Glitter bomb and other things

So I'm loving the characters and the chapter thus far, but there are just a few things bugging me.
1) Infection - why does it look like I fell in a vat of glitter-based paint? That should probably be looked at and tweaked a bit. I shouldn't look like I came back from a rave when I become infected. Even removing the appearance effect altogether is fine, since you start coughing.
2) Virus syringe. Okay, so I'm about to inject myself- no wait, I bandaged the virus away with the syringe. That should probably be fixed. You've already got an injection animation with Ping Pong Wizard.
3) Windows. Alright, this one's probably a stretch, but the windows are very clearly solid and non-transparent. I know this is because there's nothing outside the map there, but that just kind of bothers me. Not really a major issue. The first two really need fixing though. It just looks silly.
Any thoughts/comments?
