It's a numerical health bar and it's better than the previous version. The maximum health is 10, but you need some ASM knowledge on how to configure that.

Simple to use, and customize! This is probably the quickest patch ever made, but this is better to use than many other HP patches that require a million things to set up, whereas this is just insertion with asar.
