So idea of a mod is either expanding your board up to 20x20 or at least 15x20 (extending for 5-10 rows in width) permanently from the start or gradually increasing board width as you progress through the floors.
If expansion is gradual
How player's stack reacts to it? there will be empty well in the row added during expansion
How garbage lines react to it? Garbage lines will be expanded onto fresh rows as if it always was like that from the beginning (sort of sounds as win for inf ds mains tho i suppose)
How to obtain?
Since atm we dont get any mods for reaching Floor 10, it can be put in there
