Add 'donation' button

I'd love to slide the author of this app a few bucks for a cup of coffee.

I believe many of the players want to do that as well! Is there a way for me to contribute with the app?

I currently don't accept money for the app but you can contribute by designing a level :) The level editor is available on https://flowit.bytehamster.com
