I liked Picross DS much better (I finished all but a few puzzles in that), but this game is still quite good, and the 3D idea works well in execution. The only problem with this is that you can't move on past each level until you figure out all the current puzzles, i.e. if you're on level 6, and you get stuck and can't figure out every last level 6 puzzle, you can't skip them and go on to level 7. I think each level has about 6 or 8 puzzles, so if any of them stump you, you're stuck until you complete them all. Not like Picross DS, where if you finished a certain amount, it'd unlock another 10-15 puzzles.
