Thank you! That's exactly the game I had in mind while creating this. As far as I know most people didn't manage to pass the first level, even though I didn't imagine it to be this hard.
Anyway, the flip back of the switches is not a bug, it's an actual feature, ahahah. I wanted to make it like the hardware was faulty sometimes.
For the switches number there's an intuition behind them that makes it easier (I guess, or maybe it's still difficult even when you know it).
