Thanks so much for the stream!
Really sorry the directions weren't clear. The welcome letter explains the main loop. You check every compartment and toilet for anomalies and lock the doors of the wrong ones. But clearly that didn't work well enough.
I'm definitely adding a proper tutorial at the start of the shift. Player feedback makes it obvious this is needed. (upd: tutorial added)
Also funny that the full game title didn't show up :)
Thanks again for taking a chance on it.
