From Sami Salkosuo:
The purpose of Gravity One is to get the Ball to the Worm Hole past the Gravity Well. As many times as possible, using as little thruster fuel as possible. Forever and ever until the end of time. -Enjoy the effects of gravity to guide the Ball to Worm Hole.-Drag the Ball to define speed and direction and perhaps you can get the Ball to Worm Hole.-Use thrusters to guide the Ball but beware the cost of using thrusters.-Ball, Gravity Well and Worm Hole randomly placed in each game.-Infinite number of regions to complete.-Tens of achievements to achieve.-Play consistently to get a good position in leaderboards.-Enjoy marvels of the universe with In-App purchases that enable more music and background images while playing the game.-Background images from Hubble telescope.-No advertisements.
-Tested with iOS 8.-Fixed video size in Help-page.-Added console in Settings page. Using console you can change some game settings, for example gravity constant. Note: changing settings may result in unpredicted behavior.
