forum post, Nifflas, the creator of Knytt and Within a Deep Forest, may release the expansion to his upcoming Knytt Stories for free. At first Nifflas was considering releasing the pack for a modest fee, but after considering the extra work required to charge players (not to mention the fact that the taxman will take notice if he turns a reasonable profit), he's now leaning toward releasing it for free or as donationware.
Knytt Stories continues the atmospheric, exploration-based gameplay that Knytt brought to our attention, though this time there are more areas to discover and a few power-ups to find. Both the game and the editor have already been announced as free. Look for Knytt Stories at the end of August.
