Due to initial setup and development of this module it expands into a directory taking 130 megabytes on disk, thanks to deleted files still living in the .git repo while only containing 20 kilobytes of actual game assets.
Simple fix: delete the .git dir locally, do git init again, add files in a single commit. Either force push here (if possible, unsure) or delete the current repo and recreate it empty (work with an admin on chat)
