Thanks very much for playing! My intended goal was to get to give the player enough options to complete each level relatively easy but in order to get 3 fuses they needed to overload certain wires and speed up the electric so I'm glad you found that method successfull.
I completely agree with what you're saying about level 1. It was mainly put there as a tutorial but the fact you only get 2/3 fuses without pressing buttons might mean there is a way to alter the electric and achieve 3/3 on a second playthrough once you know the controls. Maybe go back and give level 1 another go knowing how to control the switches!
