I prefer use ini because it's more easy to detect a mistake . If i do an error i can check with blocknote directly on files .
For my game, i must to save
X position of tiles
Y positon of tiles
Type of tiles
Y of level begin
Y of level end 1
Y of level end 2
Number of tiles
I don't think array can save all because there is 3D only
After, program with array is faster than ini
Sorry for my english
