O.K. Buster (series)

O.K. Buster (OKバスター) is a series of brick breaker puzzle video games created by Sony. Burst Arts has owned the franchise since 2002, with most releases after 2004 being handled by them. Since then, the series became one of Burst Arts' top favorites.

Gameplay
The objective of the game is to go through all levels by clear a swarm of bricks and enemies with the use of Oracle Killers, or OKs for short. The OKs are spherical creatures who, in most variations of the game, can be summoned with the Spell "Buster Go." The player can launch the OKs at the bricks. The OKs will travel across the screen, bouncing off the top and side walls of the screen. When a brick is hit, the OK bounces away and the brick is destroyed. The OKs will disappear after a minute and the player's mana gauge will have to recharge if it shot an excessive amount of OKs. Momentarily, the bricks may reform and if the timer is set to 0, the player loses. But if the player manages to clear all of the bricks without having a few of them rebuild themselves, the player wins. At the end of a level, a boss appears with the same abilities as the player, and the player's only goal is to best the boss and complete the level.

Starting with O.K. Buster II, the series introduced different variations within the field (steel bricks, giant enemies), as well as power-ups that will enhance the OK itself. At that point, the series began to introduce different aspects to the gameplay, such as enemies disguised as bricks, Warp Gates, a Custom Mode where players can create their own field, and a Frenzy Mode.
