09/11/12: Indie production house Green Hill and publisher Ripstone are pleased to announce their newest release, Cosmic Clean-Up.

Discover space as the first cosmonaut of your own planet. Use the flames of your rockets thruster to burn your way through outer space, and go where no man has gone before. Cosmic Clean-Up is a 2D skill game where risk/reward is the main mechanic.

It’s your goal to clean up the galaxy by burning away all objects surrounding the centre planet.  Once the spaceship has been launched, there is no option to turn off the engine. Slow down your ship by counter thrusting in the opposite direction. If debris is blocking you, fly towards it and steer just in the nick of time. The fire from your thruster will burn the debris away. Steer too late however, and you will crash your ship.

The alliance with Ripstone will further advance Green Hill’s strategy to develop great games with the right partners.


Maarten de Koning, Managing Director & Co-Founder of Green Hill states "After several successful collaborations, we decided to embark on a new 'adventure' again with Ripstone Publishing, called Cosmic Clean-Up (CCU). CCU is going to be a fresh experience with an intuitive control system, distinguishing graphics and highly compelling risk/reward gameplay."

Phil Gaskell, Co-Founder & Creative Director of Ripstone says "Ripstone's focus is on working with indie game developers to bring fun and unique game experiences to digital platforms, so it was only natural to continue our productive partnership with Green Hill on Cosmic Clean-Up."

Ripstone is focused on fostering the relationship between publisher and developer to produce great games by understanding what developers want to achieve and what they need to get there.
