This is legitimately one of the best VNs I've ever played, and I highly recommend it to anyone who stumbles upon it. Also join the discord! The community is super duper cool and there's tons of theorizing that goes on in there.
Take the time to explore and go off the beaten path. The fastest way to the end is by listening to the narration and objectives, but the best way to play the game is to click basically everything all the time everywhere.
Go play it. It's very good.
