One of the more complex shooters to come from Bio 100%, this one features multiple levels with good (cartoony) graphics and four pilots to play with. Although the ships are all the same, the choice of pilot determines the lines you see before each level and the behavior of the Options.
Hayakasa - Options face opposite during forward or backwards motion.
Lulu - Options face opposite on any motion, but are always parallel.
Mau - Options stay forward on either side, but will bank with you to the left or right.
Chapel - Options follow behind you, shooting backwards from your prior location.
Game movies and more screenshots are available over at Bio 100%'s website.
