Good remake of the classic, but controls really kill the gameplay.
The original game for the N64 was meant to promote the analog stick present on that console, which is unfortunately missing on the NDS so you have to do it either with the DPAD or some combination with the touch screen, none of which really works well. The DPAD controls are imprecise and you'll have a lot of trouble even with regular platforming tasks, such as jumping from one place to another, or squishing goombas. The touch controls are even more silly, really.
Fortunately, the areas have been adapted to new controls and are easier than before, and there is more stars to collect than in original game. You also get to play with extra characters (wario, yoshi, luigi), each one having an additional special ability which mostly comes in handy when star-hunting.
So overall, it's a decent game but poor control scheme sometimes really kills my will to play further, and my finger likes to say ouch! a lot as well (but maybe it's just my DS having rather hard diagonals).
7.5/10 (actually the score would have been even lower if it weren't for mario and stuff...)
