Better Bubbles
This mod introduces significant improvements to the oxygen display system when underwater. Now, special "empty bubbles" appear on the air meter, visually demonstrating oxygen consumption. Each time a bubble pops, a unique sound effect plays, with the pitch gradually increasing as the air supply decreases - creating a sense of growing tension.
Update from August 10, 2024: Minecraft developers have officially added similar functionality in version 1.21.2, so this mod is being archived.
