Very original concept, i like the idea of having to jack boxy modules together to program the rover and the "drawer" menus are also a clever bit of interface ^^
Small issue i had was with the sensor module, i suppose that the input is a jack on top rather than on the side but there seemed like there was no way to connect it so i don't know if i didn't understand the module right or if there's a bug with it's input slot :/
Overall i had fun messing around with the game but couldn't complete much because i didn't really know much more than the basics of how the motors worked, but that's more of an issue with my knowlege than the game :p
still, i feel your tutorial mission does a good job to explain the game's mechanics :)
