Thank you so much for your feedback! Yeah, the "revealed" thing is about people walking behind the windows who can see you, so you have to time it right when you go, I even made their silhouette darker in this last patch, so its not as cofusing as it was earlier, but I understand that some may still not notice that. This feature is not in many levels though. We were kinda encouraged by our teacher not to do tutorials, because "clever games expain themselfs" but I guess it doesn't always work out XD
