Thank you for the extra detail. I'll have a play around and see if I can suss out what's going on.
It may very well just be unintended side effects of leaving the unclamped camera in. I did have a play tester suggest that I should fix it, but equally we thought it was quite on brand to have it completely broken as the 'developer' references in dialogue that the character controller isn't complete or even well designed. If that's the case, i'll just clamp the camera like a sensible developer :P
Thankfully I did anticipate some of the bomb stuff you mention, I believe I do handle an edge case if the player manages to input the correct code even while holding it, so hopefully that is mostly impossible to break :D.
