Actually, I may not do older macOS because it is out of support and it would be easier for me to code just 1 version of Skyscraper rather than 2. The latest version of Skyscraper older macOS can support is Alpha 10. Also, older macOS users won't have the same experience then newer macOS users. (By the way when I say "Older macOS", I mean versions 10.12 and below. "newer macOS" is referring to versions 10.13 and above.) And also, Alpha 10 might not support some of my code and building and things like that, and yes, I do acknowledge that it is a fairly recent version of Skyscraper. And finally, I just wanna do what works for me. I have spent many hours going into the night coding this game, and if I don't develop an older macOS version, then it'll take some stress away from the project. So, that is why I will not do an older macOS version of my version of Skyscraper. I am sorry if you were looking forward to it, but I just want to do what is best for me. But, I am not discontinuing this project. I will still develop a version for Linux, and I am gonna start doing that right after I am finished typing this post. Stay tuned for more updates on this project. Thanks for reading, and I hope you understand why I won't do an older macOS version.
