Interesting concept! I was able to beat the game after a few tries. I noticed that it was very difficult for me to pay attention to 2, let alone 3 different "receptacles" at once. I would've liked a "total" amount for the wave so I know my margin of error - losing at 39/40 feels bad, haha. Good implementation, but I think games where you have to divide your attention are quite difficult for a lot of people.
