how do i get to the level creator?

ArcticWoof, yes, that is in my plans.
If you need help right now: open the level folder. Close the game. If you see metadata.vgm file, delete it, you need the only the old-format metadata file to be present.
If you're uploading a new level: in the metadata file, change the number after "workshop_id" to be "-1";
If you're updating an existing level: in the metadata file, change the number to one that corresponds to the id of your workshop item (you can see it in the url of the workshop page).

Do not open the game yet!! Switch to the editor-alpha beta first, and then open the level in the alpha editor, and upload it!

You may have to do that every time after editing the level in the legacy branch.

hey narcatix, you should also make another index discussing about how to actually upload/update levels since the legacy version is currently broken when uploading a level or make a seperate guide for that.
