Gram Cats

High school girl Sayaka is kidnapped by the secret organization Eagle (Earth Defense Force) on the way back home. According to the organization's commander, Sayaka has a special ESP that can help fight against aliens. Sayaka acquires a supernatural ability to transform into a cat and her first mission is to infiltrate Momozakura student Academy which is a base of alien forces.

Despite the synopsis the game's main advantages lie in graphics, not in story. There are two mini-games on the way to the alien base and a special card game as well. I could not even pass through the maze corridors. And the main feature of the game is an ability to change clothes on will - that's a definite step to moe games.
