Hello!
I believe I have encountered a bug at the beginning of the game.
After the chase sequence with the black wolf, I noticed that I could return back to the catacombs entrance and squeeze through the obstacles that block the path. However, when I try to squeeze my way in back again, my character does not move to the other side of the obstacle.
I assumed this is a bug and decided to leave a comment to notify you of this matter. Thank you!
