Apple in general is being less and less kind to indie devs, making it harder and harder for their games to run on any system. Especially MACs with Catalina, Indie Devs have to pay quite the pretty penny to even get free games to run on them, which is not the case with most Windows/Linux PCs or even Google Play. (Granted, Google Play only requires $25 up front, but it still lets you put games up for free, which is quite generous compared to other platforms like the Apple Store.)
So uh, if you're gonna blame anyone for making this game hard to access, you should be blaming Apple. In general, I predict it's gonna be harder and harder to play small games like this on their devices, as a heads up.
