For people who are confused about installing unshackle: go to your root Noita folder and throw the unzipped folder into the mods folder.

If confused about finding the mods folder: Go to your steam properties, click "installed files" then click browse. There you'll find the mods folder ^w^

You will also need to enable "unsafe mods" due to how unshackle works.

(I'm making a discussion despite saying this in the comments only because the comment has a higher chance of being buried in the future)
