0B Cannon

A zero budget game by Fabio Scita.

Fend off an endless onslaught of polyhedra by draining them of their RGB components. Each color gun also corresponds to a different firing mode. Destroying enemies will charge up your omni cannon, which can harm any color.

Controls

Mouse — Aim

Left Mouse Button — Shoot

Right Mouse Button — Bring up the color selection wheel, release on the desired color

How to play

Don't let the colored polyhedra get to the rail at the bottom of the screen by shooting them with color guns and draining their RGB components.
Each gun removes a red, green or blue component or different combinations of those. Each gun also has a unique firing mode, based on its color components (red fires slow but powerful explosive bombs, green fires many small fast bullets, blue fires rays that can hit multiple enemies).
Each polyhedron that gets to the rail will drain your cannon's energy, but each polyhedron you destroy will replenish some. Energy above 100% will be converted to white energy that can be used to fire your omni cannon: a fast, powerful, auto-aiming gun to be used when the fight gets tough.
