I doubt the tiny touch-sensitive screen on the DS would work well with this game. I'm also not sure if the hardware is powerful enough for the physics simulation, though I could be wrong.
I think it could easily cope with the physics (given the complexity of games already out on the system), you could even make it 2D (which I think would work better anyway)
Given a zoom, I think the touch screen could work well... AR maker... get talking to nintendo
