Goat Simulator is an amazing game. In Goat Simulator, you control a goat and destroy a small town by running into everything in sight. The game is indeed headed for OS X, but it's not there yet, which is a total bummer. However, a new iOS game has snuck in to capitalize on the goat hype, and while it's not quite as fantastic as the original, it's still a lot of fun. It's called Goat Rampage.
To call Goat Rampage a "game" might be a bit of an overstatement. It's more of a physics sandbox where you control the movement of a goat. You can run and jump, but that's about it. There's no real objective, aside from wrecking everything in sight, and the game only really ends when you decide to stop playing.
But while things like plot are ignored, guiding your awkward little farm animal around the large stages is somehow hypnotic and satisfying. You'll topple stacks of boxes, knock barrels flying, and even take out massive objects and animals like military tanks and elephants.
Each time you hit an object you get a specific number of points, and those points are tallied towards your high score. Getting zero points offers the same reward as getting 5,000, so don't feel too bad if your point total is modest. The point here is to make your own fun.
The game is US$0.99, and it's hard to deny how strangely enjoyable it is. It's not Goat Simulator, but at the moment, it's the next best thing on an Apple device.
