Cool game. I would have liked to see a bit more explanation of the mechanics though like which symbol was a transistor. I did understand it toward the end though having played through the game a few times.
I like how the bomb was always ticking and time always felt like it was running out. It would be good to have the reading somewhere without time pressure because I'm a super slow reader and it took me a few attempts to just be able to read the instructions for both of the levels.
