Goat Simulator - Really????

Okay, so yeah, Goat Simulator launched on April 1st. One couldn't honestly expect much, and the game does come with the following disclaimer:

"Disclaimer: Goat Simulator is a completely stupid game and, to be honest, you should probably spend your money on something else, such as a hula hoop, a pile of bricks, or maybe pool your money together with your friends and buy a real goat."

But it's seriously priced at $10? It's a joke, and kind of hilarious. And I would probably play it for the laughs for about 10 minutes and then be done with it. But not for $10. I just don't know how to react to the possibility of this making some sort of actual money for the developers.

Which, by the way, it's clear they put a lot of effort into developing this. Are they students practicing their craft? That I could understand, and if they managed to make some money off of a project that helped them really learn the ins and outs and realities of game development, more power to them. But I wonder, if they're not actually new to this (and it doesn't actually seem that they are based on their publication list), then why? Why invest so much time and energy into a project they come right out and say you shouldn't buy?

Funny? Absolutely. Doesn't lessen the mild brain hurt I'm experiencing right now.
