Gravity Hook HD

There is never enough logic games it pays double about the good ones. Lets look at one of them. You must as high as possible using robotic arm, which can shoot and stick to a surface. You can stick to green, gray and blue orbs. Greens are safe, grays form clusters and if you hold them too long, it falls of and blues are really pain in the ass.
As soon as you catch them, a sequence is activated and when near each other, it explodes. That means game over. If you fall off the screen, that means game over too. This is catchy, however quite hard game.
