Wow damn really nice! 10/10 would spend time debugging a virtual mars rover again. Unfortunately could not figure out how goto works, would have definitely cut down a bunch of lines of code for me LOL. Another thing that would be helpful is the ability to insert code, currently you have to remove the lines after the point where you wanna insert.

Pretty ambitious game! The code indent with the if function was also a nice touch. Though, difficult to make the robot do what you want with the limited amount of money coming in. I guess the best strategy is to make it rotate 4 times searching for ore, and otherwise move to a different position.
