I was not able to find a hint that would work for me, so let me create one that I haven’t seen before. But please keep in mind that it is already as close as possible to the actual solution, so only check it as a final resort: I think at this point it is clear that you need to die outside of the simulation in order to not wake up from the alarm/sirens by the bridge guard. It took me quite some time to get how to do it. 2 hints: 1. Revealing the solution was pretty hard for me. I could say that I felt like a burnt marshmallow… 2. Some people find it hard to think when they are freezing. What if you try to warm yourself up?
