I am trying to get Doodle Jump to install. I find the app, click to see if it is compatible, it says that it is, I install it, and now when I run it the screen goes black and then vanishes.

I have tried & tried to get it to work, and this last time while trying, it's saying that my target OS is 1.5 and that the app requires 1.6. How is that compatible if my software is not high enough to run it?

Have I wasted my 70 cents?
