Which is totally worth it — this guy understands what the game — and its puzzles are all about. Set in a time before the original Portal — you set about doing what good test subjects do — defy GladOS and solve puzzles. (In seemingly-interconnected chambers, much like Portal.)
There’s even a different endboss that, well … I won’t spoil you with. Kudos to Hen Mazolski and the fun little afternoon.
