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 or prior knowledge. 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).
