Like many other Reverse Ryona game developers, Salia Coel makes games including facesitting, life drain and foot fetish mechanics.
But unlike other game developers, Salia makes games with Unity.
His game, 'Femdom School & Monster Girls' runs on the Unity engine, and features:
3D 1st and 3rd person perspective
A wide variety of enemies
Different enemy attack grapples
This makes him a very unique competitor in the world of 'Reverse Ryona' game developent. His game shows potential, so I would recommend you give the demo a play.
