The camera and the book text are some of our biggest issues for sure, we will do our best to fix those features so the gameplay works smoother in the future! The text sound will also be adjusted and switched out completely with something more subtle and fitting.
As for the corridor, we had originally planned for the player to be able to go upstairs, but was too rough compared to everything else so we decided to block the wall off. We should've done a better job so it was more clear that the player couldn't go in that direction though. You didn't miss anything!
Thank you very much for the kind words and for taking the time to test our demo!
