Ahh ok I think I understand now :D. Haven't really done the multi-layer thing unless it's been 1 layer for ground 1 for buildings 1 for decor etc. But I am always looking for new challenges and I think I've found a fun one. Also to keep you in the loop, I plan on making a small Zelda type farming game with your assets. Not sure, but I hope this helps with ideas for further updates as well :D. Really good work I love it.
