Fantastic.
You are God.
5/5 and 10/10 .
The game reminded me especially much of the movie Cube this time, even more so than The Loop did. In any case, lots of new content, which is always a plus. The notes left behind are ever more intriguing, the atmosphere is very gripping (especially the start and the tunnels bit) and the music outstanding as ever. The puzzles were relatively easy this time with none confusing (or challenging) me too much. Slightly more challenge would've been better but I'm certainly not unhappy at where it is right now. You once AGAIN managed to work out a new coordinate/moving system to use, which I would have sworn you would have run out of by now - excellent work :D . The digital part was rather easy to be honest, though. I'm glad to see that there will be another Submachine out in 2010 - great news, and keep up the fantastic work!
