GameStyle: "Knytt Underground is a promising start for Nifflas in the realm of console gaming. The look and sound of the game are gorgeous and easily rival the best Playstation Network games. The game itself gives players a huge world to play around but many may well feel that it lacks focus and a real sense of rewards for the skill you need to show in order to progress. Those looking for an adventure set at a slower pace will love it while others will be left wanting a bit more excitement."
Hardcore Gamer: For $2, you can get Postal, Expeditions: Conquistador, Knytt Underground, Blockland, Steel Storm: Complete Edition, and Rock of Ages.

It is in discovery that Knytt Underground manages to excite by luring your curiosity throughout its entirety. Broody and evocative, Nifflas signals the emerging rise of the indies on the Nintendo eShop, crafting experiences that rival even the platform holder’s lofty creations.
Matt of RGN writes, "Knytt is at its core, a 2D platformer, but adds a large world to explore and gives the player abilities to solve puzzles and advance throughout the world, allowing the character to dash, fly and teleport, among other powers. Each chapter of the game involves different aspects of gameplay, with the first being an introduction to the main character, the second focused on a ball form, and the third combining both together. While frustrating at times during the beginning as you figure out how each power works and controls, once you’ve got the hang of it, Knytt Underground is absolutely hard to put down and each place you explore is a fun experience."
