This is a port of a work that was originally released as a browser game in 2013.
The images and controls have been slightly modified to fit the device, but they have been ported basically as they are.
The difficulty level is set high, but no technical knowledge or calculations are required, so feel free to try!

It may be easier to understand if you play it as if you were touching a machine you don't know how to use, rather than solving it like a riddle or quiz.
