This game is very fun. I played it very late, if you couldn't tell, but despite the revolution this game brought about in thinking with portals, I feel that this game mostly stands on the writing these days as while it's a fun puzzle game too much of it, necessarily so, had to be very simple to introduce people to the concept of using portals the way the game expects, but I would've liked to see a challenge mode after the main game that included some more complex puzzles, but I can't be too harsh, this game was still pretty fun, I also just wish there was more of that amazing writing wink wink nudge nudge
