Hey ya
Just want to say hello and well done in getting the mod out before me, it's exciting to have some friendly racing with other modders
I noticed you stated not knowing how to freeze health, so I'll give you some tips
You need to go to every scenes and search for "set health", do it in order of Chapter to make it easier. If it doesn't say Chapter then you can see the order of which scene go first in the "startup.txt".
If you find the "set health" in Chapter 1, it should be like "*set health %-20" or more similar one. Just change it to "*set health %-1" don't forget to change the exact thing in the "json" file too. There are definitely more so spam the search feature and change each one in that Chapter exactly like that.
And thank you. Hope I see you around.
