Half of this year update:D 

After a half of year development, studying and searching📚 (I can say a huge thank you for explaining logic for autotile system to the following awesome video - https://www.youtube.com/watch?v=qYomF9p_SYM&t=12741s) I finally got first result of new tiling system with graphic layers🗺️.

As my primary goal is to develop the data and the system to work with tiles, for graphics I've used this https://pixelfrog-assets.itch.io/treasure-hunters awesome pack of graphics.

In future updates I'm planning to complete level editor with ability to export and import data, and rewrite rendering inside the game to use this implementation (currently it is made with Tiled).
