His hubris was his undoing! Peep my sweet build:
In all seriousness this game is almost impossible to finish (save your applause until the end, please), the enemies shoot you instantly when you move, after some "upgrades" my gun started firing cigars instead of bullets, which would bounce off things and kill me sometimes (often).
This is cleverly balanced by the R button, which I employed liberally on every level, so I'm glad you put that in.
No idea what the mask upgrades did but the lighting looked very cool and I was able to make it look like my own face (see pic) which was a nice feature.
I can tell you put a lot of effort into it, congrats on making a unique and funny game.
