The player will lose breath inside solid blocks and suffers high damage when the breath is gone.

That's basically what the mod does.
If for some reason your head ended up inside a solid full cube block like sand, gravel, dirt, stone, etc. you start to lose breath. If you run out of breath while still inside, you lose 10 HP (or 5 “hearts”) per 2 seconds, so it is very deadly. On the other hand, losing breath is always rather slow in Minetest, so you have plenty of time to escape.

Specifically, suffocation will be added to all blocks which:

• Are solid
• Are full-sized standard cubes
• Don't already have their own forms of damage
• Are not excluded from suffcation by mods

This means being “stuck” in things like stairs, slabs, glass panes, etc. is safe as it is usually easy to get out.

Awesome! This is exactly what I was going to do. Now I don't have to!

When I read the title i thought it would interface with a USB gas mask

I thought there might be a pillow involved...
This is gonna be a bummer for people who spawn inside blocks :D

I changed the name to “Realistic Suffocation”. Short name stays, of course.

I chose “Real Suffocation” because this mod works for real, as opposed to a much older mod which didn't work well and only added buggy suffocation for sand, gravel and desert sand.
