14 years later, this game is still pretty damn good for a puzzle game.
The story is good, the solo and multiplayer experience is great.
There are some chambers that are very annoying to solve, but its definitely doable.

Took me 6.7 hrs to finish the game along with my friend. That stupid paint is so annoying to navigate or maybe im just dump, but overall a great brain turner. I highly recommend playing this with a friend while yall shout at each other for answers (blind leading the blind).

Thanks steam for recommending this game to me. This is officially one of my favorite game series! Thanks to the passage of "Portal", I finally had the strength and desire to continue my own project, I resumed studying physics again and had the desire to create and create new things. Thanks for everything.
