More Portal can't really ever be a bad thing. Portal: Revolution is pretty good. Even if none of the puzzles felt very difficult, the general puzzle design was honestly pretty good, especially with the new mechanics. However, towards the end of the game, I started to realize that a couple of puzzle concepts were very overused throughout the various areas of the game.
The voice acting and writing weren't terrible, but it did occasionally make me wish I had some way of muting the voices. The story was oftentimes a beat-for-beat rehashing of Portal 2's story, which kinda detracted from the whole thing.

Overall, not a bad game, and more than anything it proves the enduring appeal and satisfaction of thinking with portals.
