Thank you so much for playing it! Saw you struggled on youtube lol. I guess there could have been more clear instructions. Blue points are output and orange ones are input but you done well there are 2 other levels I hope you finish it someday. Also we focused on something called feedback loop in computer science as a theme. Your goal is to bring the output to where input comes and create a feedback loop. You can actually see negative feedback loops at some levels when it lights green and red simultaneously.
