So I know right off the bat that the main characters are terrible people. Six people die in a plane crash right in front of them, and their reaction is, "Well, damn, now we need another ride. This sucks." Not even a hint of sympathy or shock, just wanting to get the job done. Wow. On the other hand, sometimes terrible people make better characters.
The story was interesting, but weird and left questions that I'm assuming will be addressed in a sequel.
I had to use the walkthrough, because the puzzles to raise the heads was not really intuitive.
The game is good, but I wasn't wowed by it.
