GG! Reminds me of the Portal 2 workshop levels that require you to maintain loops with the laser.
Super clean puzzle game. I was amazed by the color mixing mechanic that forces you to think ahead more.
There is more potential to explore, though. Maybe take inspiration from real-world circuit elements, like capacitors to store charge, diodes that can only pass current one way, and RC filters that can filter out colors (looks like the different colors are signals with different frequencies).
