Tashiro Masashi no Princess ga Ippai

Punny comedian Masashi Tashiro stars as the protagonist in this isekai story. A fairy wakes Tashiro up in his sleep and requests his help to save the princesses of Fairyland, whose designs are based on real minors that auditioned for the roles. Tashiro accepts the request and the fairy teleports him to Fairyland to begin the quest.

This action platformer starts off with a Mega Man-inspired stage selection screen, the difference being the stages are represented not by the villainesses, but by the princesses you have to rescue. Tashiro's movement in these stages builds up momentum, which is required to pass through the platforming challenges of the game. You start each stage with 500 health and can go up 4-digit amount of health - something uncommon among games on 8-bit game consoles. Enemies drop health upon being defeated by Tashiro's yo-yo. Power-ups for the yo-yo are hidden in the stages. These enable Tashiro to throw multiple yo-yos at the same time. Each princess is held in a maze-like castle. Upon defeating the witch of each castle and rescuing a princess, the castle will start crumbling and the game will start a 2 minute countdown. You have to make your way backward out of the castle maze before this countdown reaches 0.

The game switches to a bird's eye view for the stages involving the final witch. Before you fight her, you have the option to avoid the final boss fight which results in a bad ending, or charge forward and defeat the final boss for a good ending.
