Ozone Guardian

Ozone Guardian is a modern take on the classic arcade space shooter with colourful stark visuals and equally addicting gameplay. You defend the ozone layer against groups of evil spaceships, which increase in quantity and power each time, and you're thrown at a large menacing boss every 5 rounds. Your dodging and timing skills reward you with higher points at the end of the round, which you spend on creative Upgrades in the Space Shop to boost your spaceship's capabilities.
