Flappy Boy
Flappy Boy GBC is a original homebrew game boy game port of the surprisingly popular, and ultra difficult game Flappy Bird.
It was created for the original Game Boy in a couple of days as part of the 2014 “Flappy Jam” competition.
The gameplay is identical to that of the original Flappy Bird, you basically just need to press one button which propels the character up into the sky, all while managing to successfully navigate difficult levels.
