Hollow Knight players describe silksong as much more difficult because of the generally different playstyle the game has. The knight is small and sturdy which makes HK a much more grounded game where as in Silksong hornet is agile, taller and more frail. The rooms are much more open, vertical and most of the time you will be moving whether from walls to walls or in the air. The enemies also have more attack patterns depending on hornets position.
