Steam Workshop support is now live!
You can now upload your own levels from the level editor to Steam Workshop, and play levels created by other players from the Workshop menu in the game.
To upload levels, just hit the upload icon in the level editor toolbar. The first time you upload a new level, the Steam Workshop page will open in the Steam overlay, giving you the opportunity to add a description to your level.
In the main menu, the "Workshop" menu is now enabled. This menu will show you all the Steam Workshop levels you've subscribed to. By default you won't be subscribed to any, so the game will pop open the Steam overlay and take you automatically to the Workshop page where you can subscribe to levels. When you return to the game hit the Refresh button and the levels will appear.
As always, please let us know if there are any problems, and have fun composing tunes! We can't wait to see what the community creates!
