I'm desperately trying to find a game I played on here a couple of months ago. It was a side-scrolling action game in which you had no weapons, you could only run and jump and bounce off walls. You were a human (referred to in the game as a "fleshbag") trying to collect parts to make a huge gun to destroy this big alien thing that was trying to eliminate you with various weapons. And all the while, the AI of the game was insulting you endlessly, describing how worthless you are. It also happily admitted to being a bit of a Portals rip-off.
I'd be grateful if anyone could point me in the direction of this game. Thanks!
