The FirstAdventure was written for those who prefer to learn things by trial and error rather than reading a complete documentation. It was also written to give everybody a first cartridge to get started with.
You will receive a functional but quite boring cartridge that you can play with. The cartridge as it is should never be released but if you beef it up with media and a storyline you might actually have your first cartridge.
If you want to do more than this basic cartridge there is (to my understanding) hardly a way around learning some basic programming skills (for example “if then else” structures). This is where this page refers you to the tutorial that might help you to get a deeper understanding of the mechanisms involved in programing a Wherigo cartridge.
