So yeah I made a Flappy Bird clone called Flapping Bird. And before you hate me to death, I at first was just trying how hard it was but then I liked the artstyle I did (yeah yeah I know, I'm so full of myself) so I published it. So go check it out if you want to. If not for the gameplay, then just to see how it looks on your screen.
