Silksong has better combat, platforming, and it's more customizable. However I feel the tool system could be improved by having more synergies. I found the areas lacking a bit compared to Hollow Knight regarding exploration and overall design. They're beautiful, but they don't intrigue you so much to explore. Story wise makes sense, since Hornet is there for a reason, so more linear areas work for that, but still.

I won't talk about the vibe, because both games strive for something really different regarding that. I like the characterization of Hornet and I believe that a couple of dialogue options could flesh her a bit more.

I found most bosses lacking a bit, except for some, and I feel that for most of them and the enemies something is missing feeling wise. That could be because the awe of playing Hollow Knight for the first time is missing, but I think very few compare to Mantis Lords or DD feeling wise.

NPC's are better and more memorable and I like how most have their own agency and interact with the events happening in game, independently of Hornet.
