Cannon Ball is Another fun Hudson Soft title. There are balls bouncing all around the room. You shoot a... spear? electrical lasso? something, anyway. You shoot it straight up into the air and if it hits a ball (kind of hard) or a ball hits it (kind of easy), it splits into two smaller balls. Repeat until the balls can't get any smaller, and continue until there are no balls remaining, then move on to stage 2, where they add an extra ball.

This is my first PC-8801 Hudson Soft game. The cover has a nice style to it.
