Lets 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.Sound effect materials used- OtoLogic (CC BY 4.0)- Sound Effect Lab
