The game got a lot of crap when it first came out for being glitchy, but it was because they rushed it out due to the massive exposure with Let's Players discovering it and playing it. I remember back in the day, even when playing it with all of it's issues, I could tell it had a lot of potential. I knew they would work out the kinks. You kinda have to give props to them for going full 3D also, as it's probably a lot harder to put this game together than the Visual Novels on this site.
But yeah. It's super polished now. Everything is better. Graphics, gameplay, stories... There's a ton of content, and a bunch of different story-lines based on choice. Every time I play it, I find something I missed in all of my other play-throughs. I can't recommend this game enough. It's the reason I found this website. IMO this is the most ambitious and well-done game on this site. The latest update is frigging hilarious.
