Shake that gravity

I took a lot of time to make the sprites (more than 1h to be true) and I didn't finish. Then I coded in less than 1 hour that gravity thing. Then got troubles to test... Realised I didn't install Android SDK... Rushed download and compile and then uploaded this tested only once toy here.

Might update later to make add a version that looks the way I actually wanted it to look.

Feel free to download anyway, but I have to warn it's kinda boring :p
