A retro-style game composed of pixel art.

Operate the hero and hero Zumiman to fight Suwill, a monster that pollutes the water source.
The weapon is a water balloon.
Clear the stage while exterminating Suwill with the stream of water balloons.

There are 50 stages in total.
Items that strengthen and recover Zoomy Man can be purchased at the shop every time the stage is cleared.

It's a retro game design, but there are multiple difficulty levels.
[Reiwa], [Heisei], and [Showa].
You can choose the difficulty level you like and play.

[Reiwa]
It will be saved in the middle of the shop. You can try again even if the Zoomy Man is killed.

[Heisei]
It will be saved in the middle of the shop. When Zoomy Man is killed, the save disappears and it starts from the beginning.

[Reiwa]
There is no save on the way. You need to be prepared to play 50 stages at once.

Imadoki's game is not easy, but it is recommended for those who want a retro play feeling.
I hope you will become a zoomie man.
Everyone is a hero.
