I've uploaded the latest versions of the game (jade.apk) and the Java source (jade.zip) to the code repository for the project
Let me have any feedback on the game you care to send me.
Some of the style of the Java code is, I confess, rather untidy. It's been through quite a number of different generations of compilers and build engines since its first origination in 1993, and I'm tidying it up as I go along.
Android Studio: Don't do it this way, do it that way.
Me: Oh, get a grip. It works, doesn't it?
