Hi! Thank you so much for your kind words — it really means a lot to me as the developer. I’m very happy that you enjoyed the atmosphere of the game!
About the part where you got stuck: there’s a small door on the floor in the director’s office. To progress, you just need to press CTRL to crouch/sit and then interact with that floor-level door. It’s easy to miss, so no worries!
If you ever decide to give the game another try, I’d be really glad to hear your thoughts again. And thank you once more for taking the time to write this!
