Solid mod with engaging and interesting puzzles that use the addition of a time portal very well. As a time travel nerd the version of causality they used was a little nonsensical and took a bit to figure out, but several puzzles rely on that specific version being what it is and the game uses it well mechanically.

Don't expect a story/writing on par with the Portal games. I mean, don't expect that for *any* game, but here in particular think of it just as a series of puzzles with a *very* loose connection to the main story with no real storyline.
