Smile [GAME][2.2+] Powered Descent - a spaceship landing game

Hi, I've recently released a new game, called Powered Descent. It's a spaceship landing game, in which you'll have to safely land on different planets and moons, while avoiding all sorts of dangers, for example volcanoes. In free version there are six levels from Moon and six levels from Mars, and in paid version there are also Europa, Io, Titan and Mercury, six levels in each.

Here's a video:

You control the spaceship using either tilting controls (accelerometer) or on-screen buttons.
Here's a link to the free version of the game:

I hope you like it, and feedback and ideas are welcomed! If there are any issues, I'll see what I can do to fix them.
