About this project
What does Aqualung add?
Aqualung

Stay underwater much longer in Minecraft survival.
Aqualung adds a simple underwater breathing item for Minecraft.
The Aqualung is worn in the head armor slot and greatly extends the time you can stay underwater.
It gives an OXYGEN_BONUS of +49, which means air is consumed about 50 times slower than normal.
This makes underwater exploration, building and cave diving much easier, while still keeping the survival feeling of vanilla Minecraft.

Why Use Aqualung?
Vanilla underwater gameplay can be frustrating when you want to explore, mine or build for more than a few seconds.
Aqualung gives you more time underwater without removing the survival challenge.
You still need to care about air.
You just get enough time to actually do something useful below the surface.
