Cow Tipping has been live on the Android Market for a month and a half now! It's been pretty exciting to see it happen. Granted, it's my first app and it's extremely simple, but I'm happy with it. The app's making about a quarter a day now in admob ads and has almost 2500 downloads, 36% retention. Trying to push out an update - possibly tonight - when I get to it.

Notes on some features to add:

Back button - from finished gameplay
Hint - for new users
Size Optimization - drop from 3.6 MB to under 2.0 MB
New finishing messages
Sheep - to distract from tipping the cows
Levels with different objectives, background, etc.

Any suggestions? How can I make it something worth using?
