Owl Run is a concept for a super casual mobile game.
The game concept is really simple: the user controls a little owl in different stages by simply tapping on the screen. On each tap the owl fly higher, but the user have to constantly tap otherwise gravity will overcome and the owl will fall.
In each stage the owl must avoid all the obstacles and gather the required number of gems before proceeding to the next one. Once you complete a stage the user can replay it every time he wants in an endless run.
