(Android version )Ok so box code for ghost girl is stuck dost work when putting correct code one some dialogues are stuck I try to progress the rock for shed key is no where to be found to get lader and can't progress from there and the security guard mission is stuck to get in vent in security room
code for the box is 472. Shed key is lower left of the woods, it's blocked by one of those root hands. Need the rupee from the shop to get rid of it. For the security guard you'll get a scene if you're on the other side and try to get out (It connects to the same vent you used to get out of the freezer.)
Only the shed key is for main plot progression.
