+OneLoneCoder.com - Code-It-Yourself! Flappy Bird
+"You asked for it... wait, no one did, ever..." - @Javidx9
+
+Disclaimer
+~~~~~~~~~~
+I don't care what you use this for. It's intended to be educational, and perhaps
+to the oddly minded - a little bit of fun. Please hack this, change it and use it
+in any way you see fit. BUT, you acknowledge that I am not responsible for anything
+bad that happens as a result of your actions. However, if good stuff happens, I
+would appreciate a shout out, or at least give the blog some publicity for me.
+Cheers!
+
+Background
+~~~~~~~~~~
+Look it's Flappy Bird, OK? Press Space Bar to Flap. Get a high score.
