Wasn’t Knytt Stories fun? Nifflas hasn’t compiled a new third party expansion pack just yet, but there are quite a few candidates for it popping up over on his forums. Here’s one that I really liked: UncleSporky’s funny and imaginative “”http://nifflas.ni2.se/forum/index.php?topic=1451.0">Don’t Eat The Mushroom". It may only be a couple of minutes long, but if you’re anything like me, chances are you’ll be playing through it twice!
If you want to try a few more third party levels, Nifflas’s list of favourites might be a good place to start. And feel free to post your favourites in the comments! (or plug your own mod, that’s cool too :) )
(Thanks clysm!)
