A little about me...

Sonny Roovers

"People often feel my work before they see it. I’m like an invisible architect of game feel".

I specialize in the designing systems that improve the experience for the player, like economy, progression, combat, and locomotion. My process runs from documentation and rapid prototyping through iteration, keeping every discipline in sync at every step.
