Working on a game and I need a single word that represents the 5 senses: smell, touch, taste, sound, and sight.
At the moment I'm using "perception" which I don't think is adequate.
Have you considered senses?
It may be obvious, but I think it fits your needs nicely.
Sensorium might be the word you want.
Definition of SENSORIUM
: the parts of the brain or the mind concerned with the reception and interpretation of sensory stimuli; broadly : the entire sensory apparatus
I am thinking of the word stimuli.
However, a more suitable word is the ancient Greek word αίσθηση (aesthesee):
The Greek for five senses is πέντε αισθήσεις (pente aestheseis).
This is the Greek word from which the English aesthetic derives. Also spelled esthetic (US).
Aesthetics is a branch of philosophy involving indulging of senses to appreciate our environment.
I would not restrict the aesthetic senses, but if you need to you could coin the word penthesys, or pentesthesys.
Otherwise, in a computer game, one could have the basic aesthesis/aesthesys, and progressively gains further awareness or higher consciousness, gaining more talents of aesthesys.
