Flappy 2048 is a webgame created by hczhcz in March of 2014. It is currently playable on the github page. There are 2 different versions of this game:
Flappy-2048 (March 2014)[]
This is the original version created in 2014. It's basically normal flappy bird, but when you collide into a pipe, your block score gets reset to 0.
Another Flappy-2048 (April 2014)[]
This version is more of a flappy bird game than the previous one, with the goal of matching your number with the one in the wall. If you match your number with a different number or hit the floor then you have the restart.
