How would I get the red key in the room full of traps in Qasir Al-Wasat?

Question

In Qasir Al-Wasat: A Night in-Between, I'm stuck in the room full of traps. I'm trying to get that red key, not à la Indiana Jones And The Raiders Of The Lost Ark since the traps are on the floor all around the pedestal.

I've looked throughout all locations and found nothing which could help, so I believe this is a puzzle based on logic, timing or skill. If this is not the case, could you point me to the rooms where I could further investigate?

When the hero dies, the screen gets brighter, and I still cannot see any missing pressure plate.

Answer 1

If you look closely (its easier with more brightness) there's a this pressure plate missing in the back.

Here, I made a video showing how to get the Key...
