Too much is not clear. For example, the "Hall Monitor" mission: It was not clear that I needed to wire a "Sensor Input" to an "Antenna Output"... Especially since the terms "input" and "output" are confusing here.
I am also having trouble with the "Navigating by Antenna" mission. If I set my motor speed to 4, it drives past and beyond the goal, without registering it. If I set my speed to 2 (and adjust my turning accordingly), it turns at the first and second point as expected, but does not detect the third--driving past it and hitting the wall.
