A downloadable game for Windows and macOS

Turn your body into the controller in this fast-paced, Fruit-Ninja-inspired action game! Using real-time computer vision, slash targets out of the air, and duck and leap to avoid bombs. It can be played in single-player or 1v1 split-screen.

Perfect for quick play sessions, parties, or just burning off some energy. This game blends physical movement with arcade-style intensity, and only requires a webcam.

Developed by Jaime Walter, Jay Katyan, and Kristian Prifti, originally as a final project for Computer Vision (CIS 5810) at the University of Pennsylvania (2025), and now released for everyone to play.

Instructions: Make sure to have a webcam. Select options in the menu by closing your fist. Whatever part of your body is highlighted in purple must touch the white target, while avoiding that any part of your body touches any of the red bombs.
