Just launched my first game, Keke On The Run where you control an auto-rickshaw and avoid other vehicles while collecting fuel cans on the way.
Most of the logic was done using playmaker and the ui was done with nGUI.
For a first game, it was a pretty interesting experience. Fun most of the time and annoying at other times.

Play and have fun.
