Kitten Rampage seems like a game that is directly copying Goat Simulator, but with a Kitten instead of Goat. If that's your thing it's now on Linux.
I didn't quite "get" the fuss over Goat Simulator anyway and now we have a copycat in the form of Kitten Rampage, oh dear.
This could quite easily win my "stupidest game of the year" award.
