Taleroth: Because you think death is a fail state?
StingingVelvet: No, because the way you figure out the "puzzle" is to walk into it and die. Then you know next time not to walk into it. Then you walk into the second one and die, then you know it's different. You are not figuring anything out using your brain, you are just learning where to walk through negative feedback.
Figuring out how to not die is more complex than simply "not walk into it."
The crusher trap seems a popular topic. As an example, it's not the crusher trap that's the trick. It's the soldiers following it and realizing you use the crusher trap against them.
Or the swinging bear traps earlier. Go forward, die. Go forward to trigger, then run away, die. Okay, now figure out how to avoid both.
Yes, you figure it out by walking into it and dying. But so what if you figure it out by dying or if you figure it out by losing your block? Then you go back, get a new block and the puzzle resets. It's just a reset mechanism.
