A hyper casual game, Crystal Keeper features you in an orthographic eagle's eye view of your spaceship with intuitive controls to swerve your spaceship around the circle and shoot in the direction that you are pointing. Crystal Keeper is a unique fast-paced arcade shooter. You must protect your circular perimeter from an endless wave of incoming asteroids as you soar through the vastness of space.

Direct the arrow clockwise or anti-clockwise to guide your spaceship.

Aim and shoot down the asteroids before they escape your protection.

Collect as many power-ups as you can to add to your firing power.

Crystal Keeper was created using incredible designs and tools.
