Nice one! Daz a lot of humans and BTC. TO THE MOON xD
The game is really challenging on normal difficulty, but it is fun to shoot everywhere and collect the enemies.
I don't know why but the menu music is very reminiscent of "Comedy Equals Tragedy Plus Time" from the Portal 2 OST. It's like a sped up version of it. Sounds nice tho!
Very nice entry overall!
