On Constant Delay is a narrative-driven educational game that explores the daily struggles of living with Obsessive-Compulsive Disorder (OCD). In this game, you step into the shoes of Leonard, a man whose life is deeply shaped by intrusive thoughts and compulsive behaviors that hinder even the simplest everyday tasks. As you navigate Leonard’s world, you’ll encounter scenarios that trigger his symptoms, illustrating how overwhelming and paralyzing these moments can be. On Constant Delay does not seek to provide medical solutions or treatments. Instead, its goal is to raise awareness, challenge the stigma surrounding OCD, and foster empathy for those living with the condition. We hope this experience helps players recognize the complexity of OCD and helps those affected feel less alone.
