Thanks for the review! Yeah, I thought that puzzle might trip up some people so I trimmed it down to 3 buttons so people can easily just guess at it. It required paying attention to some of the posters/scribbles around the lab (power must be on, safety hinders innovation, etc) and the words beneath the buttons, which tells you which button is which (ie, safety, power, innovation). Those should give you the clues to the correct answers for the buttons. Hopefully that helps with understanding the puzzle haha! I'm glad to hear that you liked the ending. That was my favorite part to make!
