Gravity Guy is a very entertaining and challenging game. I guess we could call this game a platform game mixed with one of those run-as-far-as-you-can games. What is interesting about this game is that the controls are incredibly simple. The action is constant and the game is very challenging. The premise is simple. You escape from a prison and have the ability to invert the effects of gravity. So, when you activate this power, you will fall, but to the top of the screen. Once you touch ground again, you can re-activate the power and turn gravity back to normal, which will cause you to fall to the bottom of the screen. You can't do it while in mid-air. You have got to touch ground before you can do it again. So, while you escape, there will be countless obstacles that you have to pass, and the only way you can pass them is by walking on the ceiling, and then on the ground, and so on. Basically, you can play this game with one finger in your left mouse button or the space bar.
There are different game modes. I played the story mode for some 10 minutes. I lost several times, but there are checkpoints. I advanced through a good part of the first level and I found myself repeating the same parts over and over again. That is how challenging this game is.
