Twinkle Star Sprites

Twinkle Star Sprites is a 1996 scrolling shooter arcade game developed by ADK and published by SNK. It was ADK's last production for the Neo Geo. Two players are each in separate, side-by-side, vertically scrolling levels. Combinations of shots and timed power-ups damage the other player. These attacks also serve as counters to the opponent's attack.

There are two types of standard attacks: a normal shot and a charge-up shot. Each character starts with two bombs, which clean the screen while briefly granting the player invincibility. The two players' playfields are separated by a vertical bar; each playfield is independent of the other. Series of enemies arrive from the top of the screen. The player must destroy them in chains (combos), which will send one or more fireball projectiles the opponent's screen (Normal Attack). Shooting a Normal Attack several times reflects it back as a glowing Reverse Attack. If Reverse Attacks are reflected again, a number of powerful counterattacks in the shape of one or more indestructible enemies appear (Extra Attack). Reflecting many Reverse Attacks at once can instead summon a boss (Boss Attack).

Twinkle Star Sprites was developed by ADK.

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 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 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 Windows, Mac, Linux, and asm.js was released as part of the Humble NEOGEO 25th Anniversary Bundle on December 8, 2015. It was released on Steam on May 26, 2016; and on GOG.com on May 30, 2017.

Pony Canyon / Scitron released a limited-edition soundtrack album for this game on February 21, 1997.

In Japan, Game Machine listed Twinkle Star Sprites on their January 1, 1997 issue as being the fourteenth most-popular arcade game at the time. The game received generally mixed reception from critics since its release in arcades and other platforms. However, fan reception was positive; Readers of the Japanese Sega Saturn Magazine voted to give the Saturn port a 8.85 out of 10 score, ranking at the number 118 spot, indicating a large popular following. Readers of the Japanese Dreamcast Magazine also voted to give the Dreamcast port a 7.58 out of 10 score, ranking at the number 307 spot, indicating a popular following as well.

Both AllGame's Kyle Knight praised the audiovisual presentation and frantic gameplay, stating that Twinkle Star Sprites is "a refreshingly innovative title that manages to pull its seemingly incompatible elements together brilliantly." However, Knight criticized the amount of slowdown when too many objects are present on-screen. Consoles Plus' François Garnier also praised the presentation, visuals, animations, audio, longevity and playability. IGN's Colin Williamson reviewed the Dreamcast conversion, commending the addition of extra options in the release and multiplayer mode but criticized the low-resolution graphics and stated that playing single-player modes were not appealing in a long-term.
