You can't make it through the maze moon with the shield. You need to unlock the rover for that moon, same with the checkerboard moon, you need the jetpack. The builder moon you need to unlock the builder. The small moon that is directly in front of the ship when you launch from the planet is the moon you must do first. Use the shield to get through it, should take 2 seconds to walk to the next spark. You can see a shield hint in the screenshots on the page for the small moon. Each moon was supposed to be only solved with one type of tool.
