Works on OSX Yosemite 10.10.5

I had bought this game when it first came out, then I updated to OSX Yosemite and it just stopped working. Would not open. I contacted customer support since this app has not been updated in a while and I got no response from them. So I ended up unistalling the app then reinstalling it again and it works perfectly fine!!! I am running this on a Mid 2011 iMac, 27-inch, 2.7 GHz Intel Core i5 wih 12GB ram and it works flawlessly.
