Ghosts only spawn in one location and If you keep walking around you won't be able to find them as easily because of their speed. The sound of the shotgun Is something I have noticed and will be working on an update very soon. The vending machine Is unknown and I haven't seen that Issue before but I'll take a look. On the other hand, the UI Is difficult to fix because of the way the buildings are they are higher than what the camera Is set at meaning no matter what layer It's on It will still clip through the building. Hopefully, we can fix this In the future but anyway Thanks for playing. :)
