This was released back in December, but it looks like it missed most of us (here) by: Flexuous Avifauna. A decent, hard as nails 16K Flappy Bird game. Page at Perfect Pixel. I'm still at the stage of wondering how to get more than 2 gates, but the evidence is out there that it can be mastered (though maybe it's rollback).
The columns move in whole attribute blocks, but it plays well and is fairly polished.
