The epic Flappadiddle-Doo is now available on 3DS Homebrew.
95% of the game is intact, but the tiled backgrounds have vanished due to "I haven't added buffer-drawing to the 3DS Framework yet!" reasons.

Otherwise, it's pretty much identical.
6 worlds, 6 birds, 6 endless modes, and a whole lot of flappiness!

You can Download Flappadiddle-Doo here for Windows, Linux, MacOS and now 3DS Homebrew, too!!

(I'm going to need to make 3DS Cases, now, aren't I!?!)
