Hollow Knight base game 10/10 amazing game, hard but very fun and incredible art direction, soundtrack and gameplay.
The DLC however is tedious and difficult to a point is no longer fun, it maintains the same incredible art direction and soundtrack but the gameplay becomes much much more difficult and much less enjoyable. So 6/10 for the DLC but its free and you can ignore it but as someone nearing 200 hours and wanting to continue playing the DLC is overly difficult content that loses the magic of the base game.
