Hi, Autism Creature Simulator at release wasn't really intended to be a 100% accurate experience of what its like to be on the spectrum. I did originally have a stimulation mechanic but I cut that due to needing to make the deadline as well as making the game overall more enjoyable.
Think of it at the moment moreso as a fun nod to autism. But making an experience thats more accurate is something I'm interested in doing, but not atm.
Thanks for asking!
