CFA engine is what came out of this tutorial. It's not an official name. I thought it would be fun to name it like this. CFA stands for Contra Force Advance - this is what tutorial covers
Can't really say much since I never used Butano. If you choosing the engine, stick to something that advertises itself as an engine. What I used was just a tutorial with a simple open source demo, I built upon this and called this CFA Engine for fun's sake
