Really like the aesthetics and oscilloscope's controls are very satisfying to use.
But I think I was stuck after the tutorial, I have inspected all the items from the list, and the test code was entered. I see the countdown, but not sure what to do - the buttons and any of the switches are not accessible. Let me know if I missed something, I would love to come back to this game to continue :)
Also I really wish there was a full screen, I loved the art as well!
Great job :)
