The game itself is good, the story is well written and the mechanics of the game are good with one significant exception. The map.
it is hard to tell which level you are on, and which level the objective is on. and even when you are in the same room as the objective it can be difficult to find. the descriptions of the objective "investigate the light" are not always helpful in pointing the way. I gave up on the game after passing the objective multiple times, being in the same room and not seeing it, spending far too long looking for an item that was right in front of me, and getting frustrated. Too bad, I would have liked to finish the story, and may go back at some point, but it's not enjoyable to just spend the whole game searching for a needle in a haystack.
