Mario vs Donkey Kong 2: March of the Minis

Some enemies actually serve a purpose, so until you've properly scoped out the stage, you shouldn't wildly start whacking baddies into the next life. For example, the scarlet-clad Shyguys can walk on spikes - mini Marios cannot. So, you've got to hop on their heads and cruise across.

It's not the most intense game, or a graphical powerhouse, but if there's one thing DS does well, it's puzzle games. The first Mario vs Donkey Kong was a quiet, well-received Game Boy Advance title, so there's no reason to think this one will be any worse.
