The game is written using a programming language called Initial Programming Language.
if you would like more details on this please go to
IPL .
IPL is much more like a 1980s home computer BASIC than a modern Windows programming language, so it is easy to pick up, this means that you can change the game if want to.
Possibly even go on to teaching the kids the basics of programming without getting totally lost in the minutia necessary for commerical apps which get in the way of playing around.
