(PMGS), located in four different roomz surrounding the King's Fortress.Access to each of these roomz is blocked by Black Pyramidz
(BP).Your task is to find the Black One-Time Switchez
(BOTS) that will lower 
these BPz , and step on them.The solution of this puzzle is semi-linear. That is, there is no clear-cut approach to its solution.
It is not imperative that B follows A, nor is Z necessarily the end of the game.
So the walkthrough of this Custom Gruntz Level is by area, and need not be taken in any particular sequence.
Except (as always in a Gruntz puzzle), there may well be certain requirements in order to enter or leave a puzzle segment;
so it is up to you (the solver) to determine whether you have (or may acquire within the area)
what you need to complete an area.
