Oh god that's so adorable

sorry, i know people keep asking but what anime is that from. it seems to be everywhere now and is it any good?

Yo, figured I'd answer with a little more detail than others.

It's a Visual Novel (if that doesn't tell you anything, consider it virtual equalivent of a book with pictures). Main theme is disability or rather, dealing with it plus romance. It's very feel-heavy, adult content is there but can be deactivated.
katawa-shoujo.com/ is the main page, download or torrent there.

Doesn't matter if adult content is on or off
It's disabled either way

Oh you!

Lawdy, I see what you did thar
