Appstore version broken

I checked that my machine was capable of running this game before purchasing. After downloading the game failed to run. Customer support informed me that a number of their games do not work when downloaded from the app store. They have been "looking into it” for 6 months. If you are going to get this for mac, don’t get it through the app store, don’t get any game from them through the app store. They got my $20 I got nothing, no responses to request for refund, Appstore doesn’t answer either. Below is their response:

We are aware that there are some recent problems popping up with some of our titles on the AppStore.
From what we can see now, it is affecting the following titles:
