The game is called Katawa Shoujo and it's free to torrent, and I just played through one path of the game...in like five hours straight.
The only quarrel I have with it is that some of the artwork (only "some") is less than professional. It's still good, mind you.
I have a stiff neck. Man, I don't know how Japanese gamers do it, you know? Hitting "space" for five hours and occasionally clicking a choice--WTF.
There were plenty of humorous moments that made me laugh out loud. The story was good.
I'll have to run through the game again and see if I can capture any of the other girls--but I'm not doing that tonight.
In fact, I'm thinking about going to bed and sleeping. Damn, am I worn out.
