You have bug when closing treasure chest code. As I unerstood: there is a statement that if I am pointing on paper it opens/closes. But I accidentally went to the left and opened it at the last moment, and I got bugged at that place :)

That if a code letter is currently open, don't matter where are you now, you can close it. In your solution (box collider) may happen same thing as before. Example:
- I pressed S button (go backwards)
- And on last moment I open letter
- My position got updated (from 1st step)
- And now I'm outside of collider
It may happen rarely, but I was lucky to see that :)
