Short and innovative puzzle FPS, with a legendary legacy, not helped at all by its obnoxious fan base.

Most puzzles can be solved intuitively, and using the portal gun never gets old. The atmosphere and narrative get creepier and creepier the more you play.

However, some of the puzzles - especially the ones towards the end - were a bit weak. They mostly relied on platforming rather than creative problem solving.

I'm glad I finally finished it, but looking back, I should have done it sooner.
