The Cruciball

The Cruciball is a physically controlled action roguelike in which you throw balls at enemies projected onto a real-world wall. Journey through magical stages, collect upgrades, solve puzzles and fight bosses as you try to save your pet from the Warlock.

Stages and upgrades

The game has 9 stages, each with its own challenges, enemies and boss fights. Across them, you face 11 boss fights and more than 30 types of enemy. You can collect and stack over 40 upgrades to shape your play style and increase your strength.

Puzzles can lead to secret stages, where both danger and rewards await.

Multiplayer

The game supports single-player and multiplayer, with both cooperative and competitive modes. It can track multiple balls thrown by multiple players at once, allowing groups to play together.

Physical play

You throw balls at projected targets in the real world. A projector displays the game on a wall, while two web cameras track the balls and register hits. The game is designed as a way to exercise and improve your health, and can be set up with a laptop, projector and two camera tripods or in a dedicated arcade-style space.
