Worth every penny!
Just got my copy a while ago and I have to say I'm enjoying every moment of it ^_^.
The game is really great and the music is superb.
I would really recommend buying it.

Great game!
I've only played this as the US version, but I know it's just the same. This game is great for those who love Platforming puzzle games! It may be a side scrolling game, but it's been made so well, the side-scrolling won't matter.
I Deffinately recommend this one to those who love Puzzle Platformers. Despite it's kid looking interface, it's actually very challenging to those of any level.
