All those things are done to make game easier as I think not anyone will appreciate playing an erotic game for fun. I could do something for bigger maps like giving 200% coins for completing it. There will be an item in the game that will increase fear after consuming it.
Ghost's numbers are quite low, so it is going to be easy until then. I could add the number in the shop to know what players have and don't. There will be now addition to UV prints.
Regarding bugs,
1 - Some items are always on as they are suppose to be used by Tess's robot.
2 - I will have to take a look.
3 - It's first camera spawned by game. Not 1st one you place.
4 - Yes, the door is not closed. If a ghost sees you entering the truck, it will chase you there.
