Amazing story behind a fun game. You should definitely make a sequel with new types of nodes, and perhaps actually get some nodes that actually require programming ;)
Really great, although I couldn't get 20 on Extreme Random Attack. You should make a sequel that has 3-dimensional shapes going through a plane, and you could make even more complex shapes if they could rebuild it, or simply go with multiple choice.
