Knytt seems heavily inspired by Seiklus, mostly because what applies to Seiklus also applies to Knytt. If you like to explore, if you like to walk through nicely made landscapes, each with their own music and graphical style, then Knytt is an excellent experience. If you seek on the other hand a challenging game like his previous WaDF, then you might be a bit bored.
You have to collect nine pieces of the spaceship with whom your hero crashed onto this world. These are spread all over the place, but it’s easy to get them, you just have to walk a bit. Knytt is also full of secrets, for example the monster with the BFG (if you played Doom you know what this means) is a nicely addition. Overall, a great game if you like this sort of gameplay.
