The mystery of the ages has been solved! Today we can get a robot to move up a vertical plane using his grappling hook to attach to floating spheres! And it is terribly addictive too... How high can you go? The original game was fun, but hellish in its expectations and difficulty. Gravity Hook HD is MUCH easier to play. It is also prettier, has a better soundtrack and no doubt hides other gameplay enhancements.

Adam Atomic's "minimalist" action/arcade side-scrolling game about a man fleeing the destruction of his city is both remarkably well presented, and fiendishly addictive. Vault over the obstacles in your path as you try to stay alive and get the high score. Those giant robots rampaging in the background? They're not there to play patty-cake, so we'd keep moving, if we were you.

Put Paper Mario and Tim Burton in a blender and you get Paper Moon, a smooth, sophisticated example of how to integrate design and mechanics into a masterful casual game. It's a platformer with a twist, and with enough style and depth to keep you coming back for more.

Simplicity reminiscent of an Orisinal game but with visuals and sound you might expect to find in something more old school. Backed by an enjoyable physics engine and a simple but well-executed concept and virtually no down-time, Gravity Hook is a simple, grappling hook arcade game that borders on clinically addictive.
