Maybe I'll check it out then. It says they built it with the Unity engine, so I might as well just learn that.
Over the years, I've had to relearn, from scratch, how to build the graphical user interface 9 times. Each time, all of the previous commands were completely obsoleted and I was out of luck. I went from using Apple B.A.S.I.C. in 1983 to Macintosh Pascal to the Macintosh Programmer's Workshop and RedEdit, to CodeWarrior, then Codewarrior for System 7, then Borland C for Windows 95, to Borland C++ for Windows 2000 and Windows NT, to Visual Studio 2005, after which time I gave up! Now I am using Visual Studio 2015 and only writing console apps with no GUI.
My Blackjack program, shown below, published on the Macintosh platform from 1993-1997.
