According to the Steam achievement stats, very few people actually finish every level of this game, so I must've enjoyed it more than most because I didn't get tired of it. It did feel kinda programmatic. You'd see how the level wanted you to solve it and you'd build the solution. But the process of getting there, tweaking until it works and until you can get the Convoy is fun! Except some of them are too annoying to get the Convoy for, I didn't do those.
