Twinkle Tale is a vertical run & gun game in the vein of Commando or Mercs developed by Wonder Amusement exclusively for the SEGA Megadrive in Japan. The cute fantasy setting and lush, colourful graphics present in the game belie the intensity and depth of the gameplay, with 9 challenging levels and huge boss fights (which are played like a traditional Vertical SHMUP), Twinkle Tale is regarded as one of the most collectible Megadrive titles to never leave Japan.
