I'm following MaGtRo's walkthrough of the game. I need to lock Ewan in the server room in aisle 3 in order to get the USBs. If I'm at the thermostat and I don't raise or lower the temperature, I'm able to hide by the mainframe. If I do raise or lower the temperature, the game doesn't let me back out immediately, it takes a couple of seconds and then I can try to hide. The problem is Ewan always catches me, since this is a timed puzzle and I'm delayed leaving the thermostat.
Any suggestions on how I can hide and continue with the game?
Thanks in advance.
