Suzieus: One Doll Survives

Move: Arrow keys
Shoot: hold Z
Go slow: hold X
To repair damage, hold X without shooting.

Easy difficulty is recommended for your first playthrough. Try Medium or Hard if you can finish Easy without using any continues.

Your vulnerable spot is the center of the gradient circle, usually near your waist. Enemy bullets always collide like they're circles about 24 pixels wide, regardless of their visual appearance. Press H during play to toggle an overlay that makes the hitboxes more obvious.
