A downloadable game for Windows and macOS

This was our entry for CoMo Game Jam III.

Orbital Defender

You play as a tiny space craft defending your star from incoming planets. Use your ship's blast-lasers to destroy threats while avoiding collision. Your ship is locked into orbit around the star - you can adjust the size and direction of the orbit to maneuver around obstacles.

Each solar threat you destroy awards you a point - shoot for a high score!

The particle effects in this game are downloaded assets. Models, animations, music and design are all original.


IMPORTANT: Although this game is fully supported for use with a mouse and keyboard, it is intended to be played with a controller.

Update (Alpha 0.2.0): We've improved mouse and keyboard input and we now believe it to be a superior input method for OD.

Expand/Contract your orbit - (L Click)/(R Click)
Change orbit direction - (Space)
Shoot toward cursor - (E)


Orbital Defender (Alpha 0.1.0) - Windows 49 MB
Orbital Defender (Alpha 0.2.0) - Windows 52 MB
