Oh I really like that.

At a first glance I wasn't even sure if the levels were built with 3d objects or just with 2d graphics.

Indeed (at least IMO) this game has a nice retro appeal. At the same time the animated objects (especially the ship and the airship) blend nicely into the scene and give it a modern touch.

Do you already know how the fights/battles in your game will work? Turn based battles?
