This is a jumping action game where you climb successive stages.

By obtaining the "Goal Item" at the end of each stage, the next stage will appear above.

By reaching the top floor and obtaining the star-shaped "Clear Item," you clear the game.

The protagonist can fire soap bubbles (called "Bullet" in the game).

These soap bubbles are fired toward the location you left-click on the game screen.

When soap bubbles hit white cloud cubes, they bounce off, destroying the cloud cubes.

When white cloud cubes disappear, they drop "cloud fragments."

By collecting five of these cloud fragments, you can stock up on one "green cloud cube."

By right-clicking with one or more green cloud cubes in stock, you can consume one stock and make a green cloud cube appear at the location you right-clicked.

Green cloud cubes do not disappear even if soap bubbles hit them.

Use the cloud cubes (green) as footholds to reach the top.
