I found you, I played you, and you treated me right
I don't know how old Knytt is, I don't know anything about the developer Nifflas and it doesn't matter. It's 2013 and I think Knytt is great. You play as a little turd like creature that hops around the world like a super squirrel. It can scale walls and fall from any height without injuring itself (unless you fall in lava, well...then you're just toasted).
Let's call the bugger, "Rick."
Rick's spaceship is badly damaged. The pieces to fix it are scattered around Knytt's diverse gameworld. To help locate the missing pieces, Rick has the ability to shoot a ray of light out of its chest, which points in the direction of the most nearby spaceship part. Anyone who has played that PS2 game called Shadow of the Colossus (maybe you've heard of it) will be familiar with this sort of thing. Like traveling from boss to boss in Shadow, getting from part to part takes a bit of time. Knytt's gameworld features a medley of tricky platforming and puzzles in between each objective.
Controlling Rick and the game's general exploration is all pretty relaxing. Though I haven't put this theory to practice, it wouldn't be surprising if this game lowered blood-pressure levels. The ambient soundtrack, calm visuals, colors and animations and simple gameplay come together to create one of the more mellow and satisfying gaming experiences you can find.
While hardcore gamers may be turned off by such a concept, on the whole I feel Nifflas does a good job at understanding how to make a game appealing to any type of gamer and non-gamer. See what your buddies think. See what your grandmother thinks.
Maybe a 7.5 is too low of score. Heck, I just reviewed The Walking Dead at 7.5 and spent most of the review chewing it out. But that's just the kind of guy I am. I write about what I want to write about. The Walking Dead is a good game but in the review I liked writing more about the things that twisted my fingers than the things that massaged my temples. In Knytt I did just the opposite. But if you have to know, I feel 7.5 is a high score for such a game. Knytt is a tiny game, over before it begins. And the whole experience, while fun is actually pretty easy (the platforming and the puzzles). For a higher score it would need a bigger, more complex and deeper world.
What's this I hear about Knytt Underground....
