Glad to hear! The player won't move eh?
Again I'm in 3D and I don't have access to your workflow but gliding through your pictures, one possible issue I see is in the second image I can see that your main scene contains a tilemap and a player node, unless you changed the name for some reason, under the main scene you should have your tile node as is, but below that you should actually have your Calla Lilies scene, you put scenes inside scenes kinda like organizational units or folders.
- TileMap (this is fine I think)
- Player (This should be the CallaLilies Scene, or the Calla Lilies scene should be below this, unless you renamed it to Player?)
- (Not sure about the camera being here, in 3D we attach the Camera to the character's scene, so maybe attack a camera to Calla Lilies Scene.)
Hopefully this helped. ^-^
