This is a great game with an excellent interpretation of the original comic. That simple little terminal was brilliant! I really love programming in games, this one brought back memories of writing turtle programs in MS Logo at school. It also had great graphics and sound, the rover model was amazing and little touches like the motion of the sun at the beginning made the whole experience so polished. Definitely the most polished and complete game of the jam.
I only found two issues: the way the player is sent back to the start every time the code is re-run and the lack of deterministic physics making certain moves unreliable. The first could be solved with some sort of simple rewind mechanic but the second is harder to fix in the time allotment of a game jam. However, it might be possible to write some simple deterministic physics since the rover basically moves in 2D across a height map. Neither of these issues are critical though.
I also want to say that I used your RPG character tutorial to model, rig and animate the bird in my entry so I want to thank you for making such a great set of tutorials! Without them I wouldn't have been able to make any 3D models at all.
