I haven't bought it yet, hence I still only have the Demo version, but checking other people's packs it seems level packs are just zip files. Change the extension ".kittylevels" to ".zip", and will see a list of PNGs and TXT files.

This is just a guess, but I think the levels are sorted by the *file name* of the level, and the name of the level is defined by the first line in the TXT files ("NA,[INSERT_NAME]").

Thank you so much! I didn't realize you could access the txt file by renaming the .catlvl file to .zip. The file has NA and NA2 parameters for normal and hard variants. I just renamed all the .catlvl files to 01, 02, 03, etc.. ordering them as desired for the pack.
