I published yesterday a preview of an old game on Google Play that I developed the first time in 1985. Right over 35 years ago. In 1991 I did the first PC version, already with Soundblaster 1.0 support at this time. This version was used even in school. The last version is from 1994. The game is really very simple and is some kind of educational business simulation for kids. But as I still have some (now older) out there, I did a new version for the 30th anniversary of the PC version. This time for Android and developed with OpenFL.
You can see some screenshots on Google Play or try the preview yourself.
