First of all, please do not include paid assets in publicly posted packages. I had to delete the package attachment for that.
So, Application.LoadLevel is obsolete (no longer supported by Unity). What you need to use instead is SceneManager.LoadScene.
To make the SceneManager class appear in FlowCanvas, please open up Preferred Types Editor window and at the top, do a search for “SceneManager” then add the type in the list using the “+” button that will appear on the left.
Having done this, you will then be able to see and use SceneManager.LoadScene method in the FlowCanvas “Reflected” category menu.
Let me know if this works for you, or if you need more help in that matter.
Thanks.
