point left, colliding with an enemy will reduce the player's health to one half of a life point. When this happens, the player's character is stunned for a short while and is reduced in speed and attack power for several seconds after recovery, all while left more vulnerable to opponent attacks. Getting hit by a Normal Attack, Reverse Attack, Extra Attack or the projectiles from a Boss cost three life points. The match is over when either player loses all life points. When a player takes damage, the opponent recovers life points equal to half of the damage taken. If a round lasts longer than 100 seconds or the player does not fire a shot for more than 30 seconds, a Death enemy appears. A player hit by this enemy loses immediately (Death Attack). The Death can be destroyed as any other enemy, but always comes back, harder to kill. Additionally, if a player is successful in volleying the Death character over to the opponent's side, and Death touches the opponent, the opponent dies instantly. This is a possible, though difficult, way to win. This, of course, would require the player to be skilled enough to avoid obstacles and not fire for more than 30 seconds. Development Twinkle Star Sprites was developed by ADK. Release While Twinkle Star Sprites was initially published as an arcade game by SNK for the Neo Geo platform, SNK later ported it to the Neo-Geo AES home console on January 31, 1997, and the Neo-Geo CD on February 21, 1997. On December 7, 1997, ADK developed and published an updated version of it to the Sega Saturn, featuring an anime-style intro, tweaked gameplay, a new character and a bonus 'Fan Disc' full of extra materials. After SNK ended up buying ADK's intellectual properties, SNK released another enhanced version of Twinkle Star Sprites for the Sega Dreamcast on March 23, 2000. To pay tribute to ADK, SNK included the Neo-Geo version along with four of ADK's other notable Neo-Geo titles in the compilation ADK Damashii, which was released for the PlayStation 2 exclusively in Japan on December 8, 2008. Twinkle Star Sprites later became available on the subscription service GameTap. It was released on the Wii Virtual Console for Japan on August 9, 2011. A port developed by DotEmu for Microsoft Windows, OS X, Linux and asm.js was released as part of the Humble NEOGEO 25th
