Teatime Samurai

When your master invites you to the dojo for tea, you end up having to do a lot more than just boil the water. Ha ha ha ha ha ha. Hm. Teatime Samurai is a twin-stick arcade-style shoot-em-up where as your fight gets bigger your light gets smaller. As you use your lantern to fight the many monsters of ancient Japan, your light source shrinks. Gotta get that oil!
