Download Tutorial Designer Free Unity. 

Tutorial Designer saves you the work of extending your scripts and rewriting your Gamelogic, to built a Tutorial on top of it. Instead, you can leave everything in place, and let this asset take care of it. It combines Visual Scripting, Workflow Design and Dialogue Creation in one piece. Put together your Tutorial steps and watch the progress in Realtime, as the game is running.

If you like intuitive tools that make your life easier, but still want to keep control about what’s going on, this is your asset!
