I am getting Roborally-flashbacks here. Really great entry - I love those kind of"programming" puzzle games - getting one done in less then 3 hours is pretty impressive. Smart idea to just do it with the physics engine - I am gonna steal that for another jam :)
Talking about the physics - it's a little frustrating how slow the ball rolls and sometimes you lose even though the solution is correct because the ball didn't fall right or something.
