This is the classic lock-and-key progression Knytt Stories level. You tackle four challenges gaining a key with each one and access to the next challenge. It also helped to establish talking cats and evil machines as Knytt Stories clichés.
The design has moments of brilliance. A particularly clever section of good-versus-bad realities has you switching back and forth to navigate it. There are also some terrible design elements. In several places stumbling upon a hidden path is the key to moving forward. Worst of all, a secret area uses Nintendo property which prevents me from hosting it. Still, this level is direct inspiration for my own level, The Dying Core, and a vital piece of Knytt Stories history, so it deserves acknowledgment.
