So I’m working on a Java 2D overview type of game which Im planning to port over to Android later 
I have worked in pure Java now, but I’ve heard that using Libgdx might be the best choice because of the Androids performance and memory limitations 
My question is if I should too this and do I have to rewrite alot of my code? 
I have already made the player, enemies, animations, powerups, GUI and some more
