Flip Flap (2015)

This game is a port of the popular mobile phone game, Flappy Bird. The game is fairly simple: You control a bird (or in this version, Opa-Opa) and tap the screen (press 1 or 2) to flap your wings and go up a bit, but gravity will quickly pull you back down. The aim of the game is to fly through the small openings in an endless stream of pipes without touching a pipe or the floor. Each set of pipes you pass gives you 1 point. The physics of the game makes it quite challenging, and it is fun to compete with others for the top score.
