Vasara

Vasara is a 2D arcade vertical scrolling shoot’em up, taking place in an
alternative 1600s Japan, featuring ahistorical elements such as giant robots
normally found in sci-fi shooters. The game follows the typical manic
shooter/bullet hell concept – players (up to two in co-op) fly forward on
hover bikes and shoot enemies while trying to avoid many projectiles fired at
them. Vasara has three playable characters: Yukimura Sanada, Keiji Maeda,
and Saiga Magoichi – each specializing in a different weapon. Besides the
standard shot, screen clearing bombs and charge attacks are available.
Defeating or damaging enemies with the charge attacks makes red gems appear.
Picking these up fills a “Vasara” meter, turning the charge attack into a
super attack. Another unique feature is that players (and enemies) don’t die
after collisions. The game features six stages and several bosses to kill.
