Summarise your game!

Bullet Simulation: The bullet is constantly moving forward, so the player can only control the rotation of the bullet.
Bullet Interaction: The bullet will have different interactions depending on what is hit, it will kill an enemy, trigger a button or bounce off a wall.
Bullet Teleportation: The bullet can enter pipes to reach new areas of a level.
Decoy Enemies: These enemies do not need to be hit to complete a level, and only exist to draw the player away from the real enemies.
Shielded Enemies: Bullets bounce off shielded enemies, this action deactives the shield however leaving the enemy open to being hit.
Motion Detectors: If the bullet hits the blue beam of a motion detector, it is game over. This gives the player an obstacle to avoid at all costs.
