Unity this SpriteShape two or three years teased, and released only now, while Ferr2D five years ago, appeared in the store and the whole time have developed. Of course, that Ferr2D functionality more and more it is stable, but not the fact that you need its extra features, take SpriteShape, Yes try it, maybe you do it enough for the eyes and the ears. The same situation with the Tilemap, it is, of course, simpler than what is in the store, but for small projects and prototyping it enough.
