Reminds me of that old magnetic football game where you place the players on the metal field and turn on the power to watch them vibrate toward each other until the Quarterback breaks through for a touchdown. For this game, I agree with other comments that formations need to be saved. Also, maybe Fight Mode would be more interesting if set per soldier. The game was interesting for a couple of missions, but was repetitive so I stopped playing.
nice. simple concept. maybe offer some way to destroy debri - like remove a certain amount of debri every few levels - or after destroying a certain amount without flaw (perfect combo), remove some debri?
