If you haven’t played it, you really should give it a try. It is one of the most creative games I have ever played and is now one of my favorite pieces of fiction ever. This game is the game that made me take visual novels seriously. Before this I just though they were all typical, anime-esque romance stuff. I want to try more of this stuff.
I also heavily recommend it. But you need to play at least your first run blind; no spoilers, no “I’ll watch the let’s play to see how it is”, no info. Then you get the full vibe of the game.
I second this, it’s best experienced without any spoilers. And that’s coming from the guy who usually checks the ending of the thing he wants to try out (yeah I am weird like that).
