This mod changes the duration of levels longer than 4 minutes, and 8 minutes, and so on!
The mod adds an additional X for each doubling in length after 4 minutes.
For example, a 5 minute level is XXL, a 9 Minute level is XXXL, and a 100 Hour long level is XXXXXXXXXXL
Feel free to look at my abysmal coding skills!
Part of this code was taken from Cvolton's mod BetterInfo
