Well, I made a post about how five of them could be visualized here Visualization of the five senses - Future Game and I personally think that if the varying senses are done right the game could become quiet visually interesting. like if the game could become more stylized, with a flatter more lineless art style, the lower depth perception your species has.
but I never really considered how those senses could be gained. I think eyes are arguably the easiest since, at least from the explanations I hear (correct me if I’m wrong),
eyes first start out as light sensitive cells, then there’s a divot added to give depth perception, then a lens is formed over the eye, while different cones effect the colors your creature can see, in the most simplest terms.
this can be simulated through sculpting and possibly editing cells, the lens and cones could possibly be modifications.
taste, and touch, could go similar routes, taste is modified skin on some part of your creature, touch is inherent to the outside of your creature already, but parts of the skin could be modified to become more specialized i.e. electroreception, thermoreception etc.
hearing and smell are a bit more difficult, hearing requires a place for sound to go to while also using bones that vibrate in order to detect the sound, and the sensory organs required for smell are found in the nose which is a whole other complex organ that a would be difficult to simplify, while still staying general enough for me to be satisfied.
hearing could probably just be a template that could be modified as the player wishes but if anyone knows how ears evolved and has a better idea that would be greatly appreciated.
smell could probably be modified cells placed either on whatever surface the player likes or in canals in the creature that connects to the lungs, or any other apparatus that can move air through it.
placing the modified cells in a place that can’t breathe well or doesn’t get a lot of wind will tank the ability of the creature’s smell.
