Isometric game without tiles. Is there a solution?

Hi!
Is it possible to create an isometric view of the game without the use of tiles
Looking at this forum and stackoverflow.com and gamedev.stackexchange.com.
I could not find a friendly solution for me for isometric maps for Corona SDK. Simple solution, I mean.

My goal - the creation of such a kind as in the picture

Do you think the game is made with tiles or not?
the only solution is to use the tiles for these games?

Problem that I do not understand:
– Overlapping objects that are farther
– Change overlapping sprite when it moves around the map. When an object moves, some of its facilities will be closed, others are not. What is the logic of such a task?
– The logic of the movement of objects along a path with no tiles

Do not really want to reinvent itself that must have already decided.

If the tiles can not be avoided, I ask once again to leave links to materials that will solve the problem of isometry in the Corona SDK.
