I had been lamenting the fact that I had been leaving so many games less than 100% complete lately (namely Yoshi's Island DS and Contact), but I now have the sneaking suspicion that I should not look to break the trend by way of Kirby Canvas Curse.
After considerable swearing I did manage to complete Rainbow Run, and I must confess it was sort of satisfying to achieve some of the challenges that at first seemed impossible. But for some of the remainder, I finally yielded to my curiosity and checked a FAQ (especially since the orange plunger kept eluding me).
So, how the heck can you score 36,000 points on Paint Panic!? I can barely reach half that!
Going through the main game with the different characters several times over doesn't sound too difficult, but it does sound pretty tedious.
