It's a nice little game, but I don't think it'd work that well on DS. I was rather excited about the possibility when there were two worlds on the screen at once, since that would be perfect for the device. However, in later stages there's 3 and even 4 different worlds simultaneously, which just wouldn't work on the DS' tiny screen. I'm afraid you'd need a resolution at least twice that of the DS to be able to play this game properly.
