Wow this blew up my ears.
I wasn’t sure exactly what I was trying to achieve with the lasers and it didn’t help that I couldn’t close the email window to watch the video.
Thanks for trying the game!
In experiment one and two, you're trying to prune the organisms exponential growth to achieve the required tissue size. (8 for the first level). Note that the tissue grows back differently after repeated prodding.
In experiment three and four, you use that knowledge to build circuits without short-circuiting.
If you get stuck or just want to move on to the more complex puzzles, you can hold F12 + enter to skip a level.
Hope you'll have a chance to give it another shot.
