We are really getting a mixed review on this one, some have found the puzzle very easy and some have faced difficulties getting past the first level. For now, the conductors only fit one way and when it fits correctly the conductor will light up, if you want to give it another try, you can turn the conductors of the first level until they light up and that should glow the bulb. We have a lot of suggestions and feedback on visual indications, so that will be added in the next release with a nice tutorial to get you started. All in all, we are happy that you played our game and invested your time in adding feedback. Thank you Jakesamuellawrence much appreciated.
