Click to flap. This engine is very floaty, so it may be used for games where you don't play as a bird (a cloud or fish possibly). There is no gameplay: this is an engine to start coders off with a flappy game like a Flappy Bird clone or something else.
Code by LNCS (JacobGuy7800) Remix ideas: A floaty-flappy bird clone A flappy shoot-em-up where you have to flap and shoot A double flappy game where you have to flap up and right A triple flappy game may be possible using sprite scaling.
