it is going to be 3 levels. Lv 1 is going to be a 64x64 plate. LV 2 is going to be 4 64x plates with a 6 brick space between. This is 140x. Lv 3 is going to be 9 64x with a 6 spacing which will end up in 210x. The largest maze I have done is around 100 64x plates which detoured me from making mazes by hand now.
