The puzzle were great i couldn't tell if my solution was the intended one. Like on level 5 I had gotten a robot up to the blue button but I couldn't really tell what it did. So, i had used all of the robots to make a staircase up to the red button. But other than that searching the levels with a drone was great to try and understand what each level wanted. Great Job :D 

Cool game! The controls are nice and its fun to be able to scout the map with the drone, the only thing I missed was a way to increase sensitivity :D Nice job!
