The White Sand Resort bonus scenes are Patreon Exclusive, the version of the game here is the free public version which does not include access to those scenes. However, assuming you are using the patreon version, the walkthrough is pretty clear as I try to guide the player from the first room you start in.
I will try to update the walkthrough at a later time with pictures to better help the community but it would require me to replay the entire game on a new save which I currently don't have the time for.
