Pros:
-Looks absolutely gorgeous
-Controls are mostly excellent
Cons:
-Easy
-No jump down from ledge by pressing down and jump
-No ds features (not even a second screen, come on)
It's like chip and dale's rescue rangers on the nes with nes graphics, no throwing, no co-op, no ducking and no jumping down from ledges.
But it looks good enough to be a commercial game. Maybe if you add some ds features and tweak the gameplay a bit to make it more engaging it would be fun.
My older brother's girl friend (a non-gamer) really likes it

She even managed to beat the mouse.
It looks like you just ported a GBA game with no improvements (except the inreased screen res).
