Chromatic Battles is a 2D action/strategy game with tower defense mechanics and color-based combat. The player defends a rotating ship against enemy waves, damaging them only with bullets that match their color. It features planet-based progression, an inter-level upgrade system, and a cartoonie visual style.

A giant meteor is on a collision course with the planet Kaleida. In a last-ditch effort to save it, a desperate mission launches into space: to find and recover the 7 Chromatic Crystals, the only energy source powerful enough to fuel a weapon that can destroy the threat.

In the game, you take control of the crew of the spatial mission on its journey across planets to fins the crystals. You must defend the ship on each planet against hordes of alien creatures, overcoming diverse environments and enemies to complete the mission and secure Kaleida's future.
