Spoiler: Curious what other people did here. My approach on each step was to simply "test" some code to see what happened before attempting to solve the puzzle.

Spoiler: Curious what other people did here. My approach on each step was to simply "test" some code to see what happened before attempting to solve the puzzle. I tested `@xzoor.isTrue(0)` just to see... not very creative but it works for finding the lying guard. I used the same approach to test the last puzzle (#ship) and did: `for n in @numans n.board(@vehicle) @vehicle.fly(#3127)` which ends the game (even though this doesn't satisfy the puzzle).
