There have been multiple times where I open my eagerly awaited Chrono.gg email every night and a great game looks like it belongs on mobile. I look it up in the App Store, find that is indeed a mobile game, and buy it.
I don’t know if it’s technically possible but if it is you should really add the option to buy an App Store key for applicable games.
Trust me, we’d LOVE to do iOS (and Android!) games. Unfortunately, there are a lot of complications surrounding that, particularly for iOS. It’s something we definitely want to explore in the future, but we don’t have any near-term plans for the mobile platforms, sorry!
