Okay it worked turning off free roam after getting the letter puzzle (by the way it instantly depletes O2 when unchecking that), I'm proud to say I survived!
Oh that's a fun one! :D
Ye the free roam was a last resort, I realized that the game was a bit too hard and I wanted people to notice all the easter eggs on the radio etc.
But I guess it came with it flaws xD
Thanks for letting me know!!
