Update! Yay!
EvilEye: Done ('cept for the nose).
Sharprm: I left the colours essentially as they were. I feel the less saturated, semi-pastel palette is more fun or innocent or something, which I'm trying to use to create a contrast with the violence. I agree with you about the previous canvas, though, so I made it even taller in the update.
Souly: Thanks for pointing that stuff out. Not only were you right, but editing the stuff you mentioned led me to a whole bunch of other small things that needed fixing. Also, I don't know what was up with the AA, or how I missed that, but I changed colours just for you.
Faceless: Done, but possibly not enough.
Ben: No combo points, but added a kill-score, for better or worse (it made me smile, so I kept it).
Nova: The eyes were originally intentionally small (I was trying to break from the classic mario face), but as I usually do, I made them
too small. I think they're fixed.
Thanks guys!
I've started to worry a bit now that I've overdone the AA to the point of blurriness. It may just be my poor eyesight, but opinions are welcome just the same.
