For $12 I would just put it on your wishlist and buy it when it goes on sale for under $5.
The reviews don't sound too promising. But if it's your thing, might be worth a few bucks. When stuff goes on sale, $12 can actually be the price of a very solid game that you will get more than 3 hours of game play from. I bought Rocket League the other week for $12 on sale, that game will provide me with much more than 3 hours of fun. It already has given me more than 8 hours of fun so far.
