I haven't beaten it yet, (SPOILER)I'm on some flashback event at night where you and your brother sneak out, not the first flashback, but like the second. The camera is too much of a pain for me to bother with, I'll get to it eventually. I really enjoyed this game, the story is truly superb. The characters are done perfectly. I did surpisingly like the interactive simon says and breathing mini-games, which I thought would annoy me at first.
I agree there should be another Indigo Prophecy, or anything like it, but I'm sure it won't sell well and will never ever get a sequel.
