This game is an awesome remake to a PSOne classic. The graphics are nice and clean, it's just fairly short.
One can tell that Namco put alot of effort into making this more than a port and more of remake for the Wii. It is one of the best platformers on the Wii, I just wish it were longer. The graphics have been improved. The sound quality and music is great. The voice acting isn't my cup of tea, but I have played Sonic games, so I can deal with it.
This game is not overly difficult, but it's so much fun that I never got bored or felt like the game was too easy.
Klonoa is easy to recommend because despite it's short length, the price and effort put into it makes it worth the investment. This game is a classic.
