Gravity is a fun, free flash game where you are in control of a space ship that is set a series of missions, literally revolving around a planet. Your main tasks are to use the arrow keys to control different thrusters, which you must employ to avoid the many obstacles and to control the speed at which you approach the landing pad. Gravity would definitely make my top ten, all-time favourite, free flash games list, if I were to ever compile one. A difficult game to master due to challenging game-play and thruster simulation, I rate it highly and would recommend it to anyone. Do you love free flash games? If you answered, ‘Yes!” then I imagine you will love Gravity.
