I've just submitted my entry to itch.io's FLAPPYJAM! See it/play it here.
The game was made in Haxe over a period of two weeks using HaxeFlixel, with BFXR for sound effects, and Bosca Ceoil for the music.
I'll be writing up a longer-form post-mortem tomorrow morning, but that being said I'm quite satisfied with this as my first finished game jam entry. Two weeks went by fast!
