I'm sure our artists would be glad that you enjoyed the cats and lore!
Difficulty, however, is a difficult thing (😁). We had some testers find the fishing difficult and some find it easy -- so it proved quite hard to find a good middle-ground.
If we can find the time, I would like to go through and make planets difficulty scale further for each one, as well as some form of difficulty slider to make it not overwhelming for those less fishing-inclined.
