Shin Megami Tensei tries out a little bit of Tower of Duraga and a little bit of Sokoban mechanics to make a game that, while perfectly fun to play, does very little to do anything new. You can play as one of the three "Jack Brothers", by which I mean you can play as two of them to have fun, and can play as Jack Frost to make yourself suffer twice as badly. Now imagine it all on a really short timer.

It's fun! It is, I promise! But it's main charm stems from fun use of the limited Virtual Boy design options, and the gameplay won't do much to make you go through another play.
