GRAVBOT is a solid physics-based puzzler: You are the GravBot, a little box on wheels that can move left and right but can't jump. Fortunately, you can also adjust gravity in any direction. The goal of the levels is to collect all the batteries without running into spikes, getting trapped, or falling off into space. You also receive medals based on the number of times you change gravity, and it can be a real challenge to hit the gold medal goal. The graphics are pretty nice -- a 3D computer style that makes the GravBot look like an old Macintosh Plus computer on a wheel -- and the controls are easy to learn and fairly intuitive. The intermittent ads asking you to purchase additional levels are an annoyance, however; it would have been sufficient just to offer the additional level packs on the menu screen and leave it at that. Overall, it's worth checking out for free to see if you like it, but be aware that the 22 levels won't last you very long.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
