The goal of GravitreX for Android seems simple enough. Try to land both of your ships on their respective platforms. It is an old school arcade gravity game that has been beefed up to current age standards, and you just have to play to believe it. There are 50 levels, with 25 of them being free and the rest available as in app purchases, so it doesn't get old. You can lift and grab boxes as well as the other ship, and the advanced damage system keeps things interesting. Players even have the ability to invert controls. Another great feature is "auto hover" for when you need to switch ships.
For even more excitement, there are achievements to be unlocked, and you can even post your score to the Swarm leaderboards. This will let you see how well you are doing compared to players worldwide. Are you number one or do you need some more practice? Either way you have an excuse to dive into more fun. You either need to practice to move up, or keep playing to hold your spot.
This is great for kids and adults. Keep kids occupied during a long wait, or give yourself a break from reality. We all need one now and then, and this is a great, low stress way to relax while not letting your brain go to complete mush.
