Gameplay
While blasting bad guys, Yūichirō and Sunday can pick up crystals that can be used to buy special weapons, extra lives, etc. Miyuki-chan's shop passes by at certain points in each level. When Dream Co., Ltd. passes by, Yūichirō and Sunday can win a load of crystals or a special weapon by shooting at his rotating target. The standard shoot-em-up rules apply. Advance through a scrolling level and then meet up with a big boss, indicated by a change in music. One hit will kill Yūichirō and Sunday, but they can either earn or buy extra lives. This game also features voice samples (in Japanese).
