This is my Java + libGDX port of FlappyBalt by Adam Atomics. The original game was written in AS3 + Flixel (Source, Game). Note that if you are thinking about porting your flixel project to mobile platforms, you might want to look at flixel-gdx instead (haven't tried it myself).
I did this project to compare Flixels way of doing things vs using barebone libgdx (i.e. not even scene2d or the tween libs). I have also done this for löve2d, see this repo. All in all, a very interesting exercise in both cases.
On ubuntu/debian:
ant setup # download libgdx and extract the needed .JAR files ant run # compile and runs the code
