This game was amazing.
The first game had me hooked, as it took place in only one singular area. which I regularly don't like in games, though the first game pulled it off well, and when this game came out, I saw it would be held in more than one place I fell in love with it already.
The characters have a lot of simple designs, as in the last game, but boy does it bring the hell-like theme they were most likely going for. The places as well.
The length of this game was about 7-8 hours for me if you're very dedicated to the whole thing, and trust me if you ever plan to do the full 7-8 hours, it's totally worth it.
This game follows a new main character; Mono. Mono wears a bag over his head, which brings more mystery to this whole game. The way this game introduces Six is quite amazing as well.
The twist at the ending, which, no one thought was coming, was astounding. No spoilers here though!
I highly recommend you play this game, it's worth the money. It seems to be better than the first one in my opinion.
