Better than I expected, but far from perfect.
Gameplay:
Wik makes good use of the analog sticks and gameplay is fun. Multiplayer is enabled and the single player is solid. If I had any complaint, it would be that the game is way too easy.
Graphics:
They are great for a Xbox Live Arcade game. There's not much to say other than that.
Sound:
Sound is good, and the effects are used nicely. Everything in the game sounds like it should, but it isn't spectacular or outstanding.
Overall, Wik is worth taking a look at, and it is a much better game than what your first impression may be, but it is just too simple for its own good.
