There are very few game developers that have untarnished track records, and one of them is Treasure. Aptly named, Treasure has released plenty of hits in the past, and most of them are 2D platform shooters. Bangai-O Spirits is no different, aiming to please this generation of video gamers armed with Nintendo DS. This is a shoot 'em up game that is totally unconventional and yet cool, and if you have a weak heart, poor reflexes and shoddy eyesight, you will not survive the game easily. In most of the levels, you will find yourself facing insurmountable odds where only quick thinking (and quicker reflexes) will get you out of tight spot, one after another.
