Feel free to play with world presets to find out interesting options combinations. The presets_user folder is ignored by git, so store your custom presets there.
If the worldgen module is updated, the compatibility with saves might be broken until save data file version check is implemented.
It is quite straightforward when working on a computer (rust must be installed), just do this:
cargo run --release
You must run pGLOWrpg from the folder that contains "options", "presets", "locale" and "save" folders, so there is no need to do "cargo install".
