“Knytt Stories is a freeware platform game made by Nicklas ‘Nifflas’ Nygren (http://nifflas.ni2.se/). The game include several short levels (’stories’), and there are many new stories created by the community that anyone can play.
As a tribute to this great game, we are developing a (free) DS version of it – Knytt Stories DS.”
