If you want to disables certain parts, or disable all but certain parts, theres a config.lua inside of the folder for the mod where you can disable things to your hearts content!

Hold the map button (which usually shows descriptions) to see the name of the effect for any specific floppy disk.
Floppy disks have a chance to become corrupted, doing different or opposite effect that is generally negative versus their generally positive or neutral effects. They look identical to normal floppies however once used, corrupted floppies will update their description to reflect their true nature.

I don't see any of the worms or trinkets.
Have you tried spawning them in? Because you aren't guaranteed to get one every run.
Hi, i`m trying to install it but i`m having some issues (idk if i did it right), i'm trying to use the console to get the items, how i can see if the instalation worked as planned? Please help
You need to extract it to your mods folder in the documents folder, then enable it in the mods menu.
