I had to google H scene. Spoilers: there is no H scene in the thread I found this in. http://www.quartertothree.com/game-talk/showthread.php?t=67529
Whatever it is, normal or not, I think it's a pretty damn great parody of a pretty damn stupid game genre!
Yeah, it does exist. One sec, I have the cover art somewhere on my computer... Edit : Found it! And yes, there was only one pigeon and one swallow.
