Espgaluda

Espgaluda is a vertical shoot-em-up released by CAVE in 2003, and the spiritual successor to ESP Ra.De. A departure from the military style present in most shooting games, Espgaluda is notable for its steampunk, fairy tale setting, along with the player's ability to slow down enemy bullets, which allows for survival as well as an open-ended, bullet cancel-based scoring system.

Espgaluda was ported to the Playstation 2 in 2004, and a sequel titled Espgaluda II was released in 2006.
Gameplay revolves around picking up gems which are dropped by enemies, then using the characters' psychic powers to enter Kakusei Mode, which consumes gems and slows down all onscreen bullets, and causes all bullets shot by an enemy to be destroyed when the enemy is destroyed - known as a bullet cancel. Points are awarded per destroyed bullet, with more points awarded for more bullets destroyed. This results in a gameplay loop of collecting gems, entering Kakusei mode and destroying as many bullets as possible, exiting the mode and repeating the process.
