Brain Breaker (ブレインブレイカー) is an action-adventure/platform game released for the Sharp X1 exclusively in Japan by Enix in November 1985. The game follows protagonist Sayaka, who crash lands and becomes trapped on an alien planet by a rogue, computer defense system. The game is a side-scroller taking place in a large, interconnected world and requires the player to acquire ability-expanding items to progress.
Brain Breaker was created by Hiroshi Ishikawa, who had previously programmed the Enix-published X1 title Kagirinaki Tatakai. Development on Brain Breaker took substantially more time and computer memory than Ishikawa's last title. Brain Breaker is now considered an early example within the Metroidvania genre. The game earned praise for its isolated setting and lonely atmosphere.
