Ghost Catcher

Ghost Catcher is a therapeutic video game designed for both VR and flat-screen play, created to support young patients recovering from surgery. Drawing inspiration from Luigi’s Mansion and Slime Rancher, the game combines fun ghost-catching mechanics with evidence-based therapeutic design. Players use a spirometer, integrated into the gameplay, to perform controlled breathing exercises that translate into in-game actions such as vacuuming ghosts, charging abilities, and unlocking progression. This mechanic not only entertains but also motivates patients to complete their prescribed respiratory exercises in an engaging, rewarding way. The project includes interactive tutorials, a safe hub space for resting and personalization, and a system of upgrades and rewards to maintain long-term motivation. Built in Unity 6.1 URP with full VR (Meta Quest) and PC support, Ghost Catcher leverages modern XR interaction systems, JSON-based save systems, and scriptable object architecture to allow scalable game design. I contributed to the concept design, programming (C#), 3D asset creation, texturing, and UI, ensuring a polished prototype ready for research and clinical evaluation. The game was developed in collaboration with the Azrieli Research Centre at CHU Sainte-Justine, highlighting the potential of video games as tools for healthcare and rehabilitation.
