I liked the demo a lot, but for me its "just" backtracking the "Detonate"-Line and then activate every other swith which is not involved. I would like to have it a little bit more complicate/challenging like :
- Defuse the bomb when a pattern on an 4x4 grid matches (like 4X / 4Y inputs)
- Activate the "Defuse"-Leds in a specific order
- Add XOR/XAND/....
