I am a fan of how this interweaves puzzle and action mechanics, even though there are a lot of puzzle fans (like my wife) who will excluded by this design. The early discoveries and insights that players get to make are phenomenal. I am someone who strived to get the good ending, purely because the game signposts you towards the more difficult secrets in subtle but excellent ways, but I do think there should be a more clear distinction between the "optional" extra hard puzzles, and the slightly simpler path toward the good ending. I ended up doing a lot of extra work, and even though I don't really regret how much extra time I spent on - this game got me to decode its language without online help, something I spent multiple enjoyable hours on even after receiving all the clues - I do wish I was given more of a choice in the matter.
