yeah the major issue is how in home screen ASCII, the maps takes a total of 64849 bytes, so far. Adding dual layer would make them between 120 and 130 KB (depending of how many 2 bytes tokens such as lowercase letters versus 1 byte ones are used in the maps, one map can range from 128 to 256 bytes in size in Illusiat 13. Also, some maps are re-used many times in the game, which drags the total size down). It would make the game over 190 KB in size, more if it gets finished, so it would no longer fit on a regular 83+
