BackAlert
Warns you when hostile mobs approach from behind.

BackAlert is a client-side mod that warns you when hostile mobs approach from behind.
When danger is detected, a compact alert panel slides in from the side of the screen and shows the mob type and distance at a glance.
It stays out of the way during normal gameplay, making it useful for exploration, mining, and avoiding surprise attacks.
