I had a great time (plus plenty of terrible frustrating times) writing this game in the “Swift” programming language!
Swift is… a work in progress. When Apple pushed Xcode 8 and Swift 3, my project became unusable. It would take me longer to fix compatibility problems than it would to start from scratch, so v1.2 with In-App-Purchases and Leaderboards (which I had finished writing and begun testing) won’t be published anytime soon.
Maybe next time I deploy, I can burn all my evenings for a month to re-create the game in the newest version of Xcode and Swift. Until then, I hope you enjoy v1.1, and apologize that you’re stuck with a thirty minute cool down and no option to purchase!
