Boundary [Android]

Boundary is a two dimensional game that focuses around gravity. The game is a simple game.
Wherever the player touches on the screen the gravity of the game changes relative to the ball.
Distance is also a factor. For those of you familiar with slope, rise and run this should be an easy game.
The objective is to see how long you can least without hitting the box you can contained inside using this mechanic.

I'd like to hear some feedback and have fun.
