Hi.
Thanks for your comment, and I hope you are enjoying the game. The code is written Python, and I created a Mac and a Windows version. As far as I know, the game should run on all Macs, independently of which processor it is using (but I haven't tested it on many different systems).
As far as full screen is concerned, while it is possible to do that in Python, I don't have any plans to make any modifications to the game. (It was hard enough to get it working in one size in the first place!). I am also just about to retire, and I don't plan on making any updates to this game.
