First three doors:
If you picked up the flower, the first door will open
If you picked up the string, the second door will open
If you picked up the batteries, the third door will open.
The first two doors are simple, theres not much of a puzzle there, but for the third door, you need to enter the time into the three clocks, enter it according to the time you see in the first video
Each door only gives you one ending, dont worry, making a certain choice does not mean you missed something, each door has nothing to offer but an "ending" in the form of a youtube video.|
The last door, the fourth one.
I havent entered.
She told me not to.
