Good and bad about the second episode

[Thaliur]

And the puzzle I really hated was opening that glass door. Who would put a random wrist band on and then inject themselves with an unknown substance?

I don't know... probably someone who read the notes about the wristband that measures your heart rate and blood pressure, the door that reacts to an emergency signal sent by the wristband in case of dangerously low life signs and the substance that slows down your metabolism to a near-death state?

Honestly, I thought all the puzzles made perfect sense, except for the mixing machine. Any normal scientist or technician would have put labels on the buttons, but I guess they were all a bit crazy down there.
