Thank you very much, I had a problem with the collision box then. You could try to implement a notification when you can interact with something then. I also had problems in the shop with the magazine and the exit. Also I'd like to suggest you to improve the first person movement because it's often imprecise and frustrating to navigate. You could try to make it like in the first pokemon's games where you move from square to square. I do think this way it would be more enjoyable to navigate the first person ambience.
Keep going, I love this project!
