Let's set out on a journey to the endless ocean! How many waves can you go?

Controls
- Move only up and down.
- To attack, simply blow up bubbles and shoot.
*You can combine 3 types of controls for moving and attacking.

Bubbles
- Bubbles expand in proportion to the charge time and can catch objects that hit them.
- It is exhilarating when bubbles filled with objects collide with other objects to defeat them all at once.
- Consecutive hits increase the voltage, making the breathing last longer and strengthening the bubbles.

Breathing
- You need to get out of the water before you suffocate, as oxygen is consumed over time and by inflating the bubbles.

Shell
- Prevents attacks from the back.
*It does not protect against element attacks such as electricity.

Stage
- Each stage consists of 10 waves, and you can proceed to the next wave by defeating all the enemies.
- Each stage has a unique gimmick.
- A unique sea boss awaits you at the end of the stage.

Lives
- There are 3 lives in total, but even if you make a miss, it will recover to 3 lives if you clear one Wave.
- Even if you lose 3 lives, you can restart from the same Wave by continuing.
- A video advertisement will be played when you continue.
