I've been playing this game on and off for awhile and I love it for storybuilding! In that regard I'd like to suggest a potential feature - unless it's in the game and I haven't found it myself yet, would it be possible to set a "main character" flag to a specific cat at the user's want to prevent a timeskip / patrol / illness-related death? It would be especially useful for those of us that have found a writing tool in ClanGen! I personally have gotten attached to too many "main characters" that suddenly died on rollover, it can be a little frustrating.
The ability to save/store certain characters from various clans or saves to be reused or recycled would be neat too, but I'm not an advanced programmer and I'm not sure how viable that would be. :'D In any case thanks for publishing this! For the most part I've greatly enjoyed it!
