Hi,
Just small promotion and kindly letting you know that my first asset for game development in unity3d is published. Please feel free to check it out in case you ever wanted to develop a simple game / simulation with hair. Below are the asset's details demos on itch. There are more to come and possibly a new game published to itch using them:

It's a hair simulation , relatively fast.
