Big day!
Max wrote his first program! Using KidsRuby (the Ruby language with the GOSU library, some other niceties), he first wrote a message alert dialog and drew lines using the cartesian coords. Then, we started on "Danger Quest", his own little 2D RPG thing.
Attached some of his concept art, and a video of the first game character running around. We got rudimentary animation using image rotation going, and soon we'll have some enemies, collision detections, etc.
