LIF Steam game Unity

I do not know how to hack a game, but I know that this game is actually very easy to hack:

It would make me happy if someone would make only a health hack for it. You do not need to buy the full version, the demo is the full version with 2 maps missing. Also it is a unity game to make it easier. It is hard for me to make a hack, and cheat engine did not work for it, so it would be really helpful if someone would make a little health hack, no more needed . This should not take that long.
Whoever does the hack, pls PM me with the hack, so it does not go public. And sorry that I cannot give tips

Thanks if someone does it for me.

A little update on this one;

Hacking the game does award you nothing but bans and a place on the moderators' blacklist.
Let this be a warning to everyone trying to do shady stuff on LIF
