Just imagine if NASA were trying to get to the Moon as though they were playing a round of golf. Then you'd have SpaceGolf.
Use gravity and your booster to slingshot yourself across a level and to a hole. Each level is randomly generated, so good luck getting a hole in one every time!
Click and drag to set your trajectory as well as your boost speed, and use planet gravity to help you along your path.
You can make micro adjustments while in the air to keep yourself from cratering. But be warned, the fewer times you stroke, the better your score will be!
