Almost every possible compliment has been said in the previous comments, and rightly so, given how banger the game is.
So I'm going to talk about random things.
There's the detail of the footsteps in the water in the pond behind one of the houses, the ultimate proof of how polished the game is.
I really like the twist in the good ending. The newspapers mislead you a little at first, but with all the pieces of the puzzle together, it's so cool.
The skeleton works too well on me every time. I hate it.
Excellent game, well-deserved success.
