It's why I don't much like the genre. You're supposed to guess shit because, smart though you may be, your mind doesn't function along the same pathways as the author's. What's obvious to him may be obscure to you. Invariably, I'll get stuck somewhere, and given that the entire gameplay consists of figuring out puzzles, I can't bring myself to look up puzzle solutions. So I put the game away "for later" and never return to it.
