Here is a Cheat Engine table for Project Root.
It could support more versions, tested with v1.0.0.5.
Option:
Unlimited Lives
If it's not working, just scan for the amount of lives (4 bytes value type) and freeze it. The address is not changing when you start a new level, only when you restart the program.
