The game was quite good, the puzzles slightly challenging for me in the beginning. but once you get the hang of things, it is quite easy. I think an improvement could be made a la zero escape series, in that when you go to a past time line, the game recognizes who you saved last time and has a little reminder as to what your past actions were. A good healthy dose of mind screwing, and definitely something to continue on with if you haven't already.
