~~I've not enough informations on the next waited version to launch such a project so I think I'll stop trying modding and only produce an overhauled version for my own usage.~~
This is exactly what I do every update, as I've found modding to not be very effective with Strive. Each newest stable version I'll start editing all .GD files in the game that suit my desires. It's taken a lot of trial and error to find out which values cannot be changed or else they break the game, especially in globals.gd. Most of the .gd files in the \scripts folder and subfolders can be edited much easier, though you have to make absolute certain you don't forget to end each code fragment with quotes or else the script will run right through into the next one, and you have errors that can break the game.
