I think this is a neat game but by the time you get to the elevator puzzle, even somewhat understanding what all the symbols mean, some symbols seems to restrict other symbols by some sort of interaction and its hard to figure out what the correct solution is. i've manager to get to the main deck a few times, but that puzzle just gets extremely confusing due to the "S" symbol with dots on either end. What you state here is that symbol needs only 1 adjacent blue space. But from testing it seems like it wants adjacent spaces to do the opposite of their rule, or have no restriction, ex. hollow circle now must be filled, circle with dot and curve inside must be empty, etc.
I think what would be helpful would be aside from those practice tablets should have series of puzzles to help you learn icon interactions, rather than just one that you sorta fumble through, find the answer, leave the tablet, go back for a new random puzzle with the new symbol andmaybe figure out new interactions.
The situation rooms symbol practice seems the most apparent to need this, since it doesnt seem to do what it says it should here on the page. additionally this inversion symbol has an impossible interaction with the pentacircle as, one of the 3 must be blue and no more, but inverted one must be red/blank and no more, and if there is an inverted and non inverted pentacircle its impossible to solve.
