Launches but won’t start new game

Just downloaded to my 1 year old iMac running 10.11.6 and the game launches but when it comes time to start a new game nothing happens when I click on the level of game I’d like to start at. Maybe it’s the big weird lightsaber cursor that’s messing it up. But no luck with Apple or Aspyer tech support, and I see little chance of getting a refund on downloaded software from the Apple Store. It’s like they are saying, "come buy this great software, and if it doesn’t work though you meet the system requirements, then f-you.” How can we trust this store?
