Very interesting idea! I had trouble getting it to register my click when unplugging (maybe that area could be larger?). Other than than, great job easing the player into the game with the hints and tutorial levels.
There's been some confusion about that, you don't actually need to put down the plug to activate the components. Once it sparks you can press space to activate them. In hindsight I would scrap that mechanic. Thanks for your feedback!
