Tashiro Masashi no Princess ga Ippai — About this game
``Masashi Tashiro's Princess Ippai'' is an action game for the Famicom in which Masashi Tashiro, also known as Mercy, becomes a prince and goes to rescue Snow White, Cinderella, the Little Mermaid, and Thumbelina who have been captured by Ultramarjo. The first four stages can be tackled in any order, and you'll need to run and jump to overcome complicated scaffolding, and attack enemies with a yo-yo. By defeating each boss, you can obtain new weapons, and by rescuing four people, you can proceed to Witch Island and the Floating Castle. The operating feel changes at the end when you move on land, underwater, up and down, left and right, and you can resume where you left off from the password for each side.
