On my PC, I have a lighting bug. The lithting change when I move the camera in the corridor with all the bedrooms. I post screenshots to show you. I put a cross on one of them to show you where the bug is the most visible, but it appear in all the screen ingame.
And along to me, the opportunities are not very precises, and we don't have much time, so maybe we could have an explanation about "what does this point represent ? " when we pass the cursor on it, and of course have more time to read this.
Thanks for read me, and congratulations for this amazing game !
