In Shoot the Bullet, unlike other shoot ’em ups, the player cannot shoot projectiles at enemies; instead, Aya, the main character, must shoot photographs to clear the screen of bullets and take down bosses (hence “Shoot” the Bullet). Scores are determined by the aesthetics of each photograph taken, such as colours and bullet density, and the risk taken to take these photos. For each “scene”, Aya is only given one life to complete the objective — to take a certain number of pictures of the boss without being hit in a limited amount of time.
To take pictures, the film must be fully loaded into the camera (100%). The player can move at three speeds, the normal speed, the focused speed, and a super-focused speed which also allows for high speed film loading. When taking pictures, the player can hold the shoot button to control the viewfinder while the picture frame shrinks — this can be used to zoom in on the boss. During this time, all bullets on screen are slowed down and Aya cannot move. If the shoot button is held for too long, the film will get overexposed and Aya would have to reload the film. The player can also press the shoot button once without holding to take a snapshot around Aya. For every picture taken, Aya will need to reload the film from 0% again before she can take another picture. Only photos that contain an image of the boss (“Success” pictures) will be taken into account when tallying up the score.
Double spoiler is the sequel of Shoot the Bullet. It inherits all the mechanics from its predecessor, but adds camera orientations modes.
New to Double Spoiler over Shoot the Bullet is the option to change the orientation of the shot between landscape to portrait. The angle of the shot is automatically adjusted depending on where the player is in relation to the boss.
