One of the best fan-made portal games that I've played. The story was pretty good and the voice actors did a very good job. The ending felt a bit sudden and abrupt, but still good overall.

The chambers were all pretty well designed. Either I got dumber since the last time I played a portal game, or some of the chambers in this game were harder than the original portal games. The parts outside of the chambers were also well designed and it all felt like it could fit into the official games.
