Thanks for nice words ^^
If you go deep, remember that i used only north and east in this version and if you have trouble don’t hesitate to pm.
@Nawrot : i used it (a single 99 tiles) to simulate a city by instancing flat " square walls" as streets and add buildings upon square corners: https://www.youtube.com/watch?v=YJu6i9gG6B8 (and create multi level maze building by using z for spawn instead x, y 
) but i used the 55 squares / tile system shown at the end of tut.
