This is a Japanese-released Nintendo Game Boy game based on the Bikkuriman franchise, likely featuring gameplay akin to the original but with an English translation patch. The addition of the English patch by PentarouZero v1.0 allows for a wider accessibility. The game's plot would draw upon the storylines present in the Bikkuriman franchise. The translator's name is included, which indicates a community contribution to expanding the game's reach beyond its original Japanese audience.
