Lacking in story, but it still somehow has plenty of personality! The puzzles are alright, and strike a pretty solid difficulty, but I was kind of expecting more new mechanics that took advantage of the time travel. Maybe it's because I played Mel and Revolution before this, but when those games add new gameplay elements in cohesion with the ongoing story, returning to the same old puzzles feels regressive, especially considering they didn't even bring back elements from Portal 2 like the gels. I like the time travel mechanic a lot though, and it sure did stump me a few times! Solid experience, but definitely the least inspired of the Portal mods.
