If you're familiar with VN's then just play this.
You won't regret it.

If you aren't familiar with VN's, this is a great one to start with.
You might like it. The storylines are excellently done.

It's an adult game by the way, don't set it up for the kids.. unless they're into that sort of thing. Little perverts. :)
Seriously though, you CAN disable the adult scenes but they are integral to the story in most cases so leave 'em on.

Uses x86 32bit sound and sometimes has issues with pulseaudio. (eg Ubuntu)
try killall pulseaudio then restart KS. Might help.
Runs in 4:3 aspect ratio, so don't fullscreen on widescreen unless you can set 4:3 on your monitor or through your videocard driver.
