That old Octopus game

In the summer of 2019 I was teaching kids game programming. This game was the first example written in class so that they learn the basic concepts. You can get the entire source code, along with some class notes, on https://pls.plaureano.com/Coding/files/learn-to-code-a-game-blitzmax-in-minutes-... As we did not have the original game machine available we based this recreation on a screenshot we found on the Internet.
