These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Gameplay Derailment: Many of the early puzzles can be solved through brute force, such as programming a robot to bounce randomly around until it eventually bumps into and picks up the object needed rather than the more time-consuming programming for it to follow the walls. While you can progress this way, in later levels you will regret not thinking your programming through.
Good Bad Bugs: In at least the Color Computer version, when faced with a button on the opposite side of a wall, you could put something in your robot's grip, take hold of that item and then simply shove the robot through the wall to reach and activate the button. You could use the same tactic to drop a robot further on into a puzzle than where you were intended to start.
What Do You Mean, It's for Kids?: Although the game was designed to teach children about electrical engineering, it has proven to be very difficult for adults as well.
