Re: https://firmwaresecurity.com/2016/12/28/boot2flappy-flappy-bird-port-to-uefi-in-assembly/
points to this version of the game:
https://github.com/fabianishere/boot2flappy
There are either 2 UEFI Flappy Bird projects:
But I notice on Gitlab that there’s another active UEFI Flappy Bird game:
https://gitlab.com/square.wheel/FlappyBird-UEFI-QEMU/-/tree/master/
which appears to replace:
https://github.com/hymen81/UEFI-Game-FlappyBirdy
If I had a bit more time to spend on UEFI games today, I’d check if these two active codebases are the same, or two separate UEFI Flappy Birds.
