Only just recently played this, completed Leo's route the past October as of writing this comment.

My God, I wish I had been there when this was still being built up; I had no idea what I was missing this whole time. Even just the single route I had gone through was enough to make me feel all sorts!

Likely going to go for TJ's route next, given that, apparently, it leads into the game's sequel, Arches, and I've heard that TJ's route is even rougher and tougher... Hoo, boy!
