Across more than forty levels, Fly'N mixes platforming and puzzle-solving in a lush, colorful world. The player guides four small creatures called Buds, each with a different power, as they try to protect the World-Trees from the villain Dyer, a hair-dryer bent on wrecking their Helys. Progress depends on working out which combination of abilities suits each hazard, and on moving Helys around and using the scenery to liberate Helicia's inhabitants.
The tone is light and the visuals are charming, with a mix of action and thinking. It is a single-player game suited to players who like puzzle platformers and enjoy experimenting to find what works.
