Definitely one of the better games I’ve ever played. I hadn’t played the first that came with the Orange Box, but after much hype had to give it a shot and very glad that I did.
The concept is so simple but so difficult at times. To get from point A to point B using just the portal gun that you have. Completing a stage did have that rewarding feeling, especially some of the more difficult ones.
The voice acting was great. There were many moments that were just genuinely funny. The dry cold humor from the various robots was great. The ending of the game was amazing too. The orchestra and the original song sung by the monotone robot was perfect.
Now I have to give co-op play a shot, I’ve heard that’s ever better than the single player campaign. If you like puzzles, then this is perhaps a perfect game.
