Fly'n is a great little platformer, and one of the most gorgeous 2D platformers that I have ever played. It centers around a group of creatures which each have unique abilities, dealing with trash which is invading their homes. There's a great deal of collecting throughout the game, which is the only real source of replayability. The graphics are absolutely fantastic and smooth - it felt like playing a cartoon. Difficulty starts off very easy, but it does eventually ramp to where the final levels were quite difficult, but a satisfactory difficult - it never felt truly unfair even when it was being quite demanding.

All in all, an extremely satisfying game, start to finish. Highly, highly recommended.
