Yes, you are right, maybe there's too little or no explanation about what you have to do, we should have worked more on that but we had no time.
The main goal is to leave the room but we want the player to feel not wanting to leave it, for story purposes. We think that it's better to feel a little bit lost than explain everything because we don't want to spoiler the experience, but we didn't handle it good and the game is very confusing at the beggining. Our advice is: interact with everything you can.
And yes, we have to make the corridor more clear because there were many people that have lost in it.
Thanks for the feedback! Hope you can give it another try and finish the story!
