Knytt stories is a freeware game that was made by Nifflas in 2007. Shortly after, I made a quick little level test inside it, making a bunch of various little art as well. Over a decade later, I was contacted by a Knytt enthusiast known as Egomassive who found my level and asked if he could properly finish it. After a flood of nostalgia, I filled in a couple small gaps in the art and Egomassive put together a really fun little experience.
The attached file is a full zip that contains our level plus the original freeware program by Nifflas to run it in. Simply unzip the file and you should be able to run the "Island of Mimir" level inside of "Knytt Stories Plus".
