Obviously really creative for the time it was released and the portal mechanics are still stellar. Really enjoyed playing it but it's just so short. The puzzles are fun and the physics are great. Coming off of the back of the Zelda games I felt like I'd been trained for the puzzles and they were satisfying to beat.

Best part of the game for me was the escape sequence. The last level is excellent and feels like you've broken the game. I wasn't around on PC when this was in the zeitgeist but I think it holds up well and I'm excited to jump into 2 which I've heard only good things about.
