Wish to reduce the vision, player need to use chemoreceptor.
As you get larger the field of view decreases, do you think this should be more pronounced?
my idea is tune down make a black area around the cell, player can’t see far.
light receptor is needed to make the black area more transparent.
chemoreceptor can add color mask or object outline highlight on the screen.
I personally think that this shouldn’t be present in easy mode, a bit present in Normal mode, and noticeable to the point where it becomes a bit of a challenge on hard mode.
