Cheat Engine

[pulmo]

I'm an absolute beginner at cheatengine and I've been trying to get some sort of infinite health in a minigame in Night in the Woods called Demontower. The problem is that health is represented with hearts, and 1 heart goes down everytime you take damage. For every level, your max health decreases, so while in Level 4 you have 7 hearts, in Level 5 you have 6.

I've looked at multiple finding unknown values guides but no matter what I do I can't seem to find what I'm looking for.

Mainly I'm looking to be able to gain NO damage from any of the enemies, like some sort of godmode. I would appreciate any help or directions on what I should do. Thanks!
