Duh
A puzzle game related to portals, gravity, momentum or whatever: CHECK
A character that's lying/keeping things from you: CHECK
You're a part of some sort of experiment: CHECK
In the end they want to kill you: CHECK
Unfitting, pretentious talk in the middle of things: CHECK
IT'S ALL THE SAME SHIT. Please, please try to be more original.
I liked the puzzle though. I wouldn't mind some bonus, actually difficult levels just to waste a few more hours of my life.
