Allthough I liked the nes and gameboy style. I think this new look will benefit your game ! I also made a gameengine switch, from Cocos 2D to Libgdx and you learn a lot new things along the way…
I will miss the Game Boy style too; I'm still contemplating adding an option to switch between the two, but that'll come way later.
Switching engines is tough but definitely educational, and so far, definitely worth it!
