Gameplay
Instead of the typical lives in traditional shooters, the player is given a pool of life points (initially 3). The player loses 1 point if they are hit by a bullet, 1/2 point if they collide with an enemy or are hit by a non-bullet attack. The game ends when the player has no more life points. Life points can be restored by items, and the maximum life point is increased when reaching certain scores (default 20 and 45 million points).
When an enemy is destroyed, it fires a yellow "counter bullet" that is smaller than the regular bullet fired from an enemy. If the player's familiar is hit by a "counter bullet", the player's item counter is increased, which leads to an increased score. Stage bosses do not fire counter bullets.
