Game: N+ (DS)

N+ is based on a flash game, where you play a ninja who has to jump around a side scrolling level, opening doors in order to enter them later. It's a simple yet compelling concept as you grapple with the physics of the tiny character in your control, all the time avoiding mines, missiles and robots.

It's also perfect for holiday, bite sized gaming at its best. It does suck a bit that you can only save every four levels or so since some do take time, but that's just something that has you coming back for more as you find yourself drawn into the whole one-more-try pull that such micro levels have.
