Southern Mexico - Xibalba

being daft, I didn’t figure initially that you can put the creature head on the turn thing and unlock it in the first of the two circle machines. If you do this, it unlocks the machine and you can turn the circles. However, I didn’t approach the creature body from the paws so I didn’t trigger the head attachment. So, not being able to move the machine, I figured I needed something else or to solve some other puzzle first, so I continued the level.

After doing all the rest and getting the other skull and enabling the second circle machine, it was clear to me that all I needed was to put the head on the first machine, however, I activated the second machine first and then went back and activated the first circle machine. This triggers the whole bit to open in the middle and fire etc. etc.

On this first go, I didn’t know I was on a timer and when I got down to the middle it had closed up again. however, you do not another chance to re-activate it. Both circle machines are locked and wont move. I claim this is a bug and you are stuffed. I had to restart the whole level because I didn’t make any saves

On the second play, I solved the puzzles in the “correct” order and when you flump the timer, you can simply re-activate the first circle machine.
