This game seems dark, yes, but with a clear logic... at the beginning. Solve several not-so-difficult points of history and... then you're stuck! Try all the option you have, nothing to do. Then go to read a walkthrough and discover that several scenes before you did not the correct action or you have done it in a wrong sequence (but it seemed correct). Luckily I use to save almost every step, so it wasn't so hard to find and reload the "crossroad", but then I have to follow, step by step, a walkthrough, or probably I have to restart the part several times. It is not so much fun to do again the same things more and more times...
