I’d say cuphead has overall better boss design even though dr Carls robot can go fuck itself and dr Carl too.

Silksong has beautiful story and better platforming.

Both are very very hard games.

Yet my, at the time, 5yr old finished cuphead with dlc on normal. Now, at 9, he’s beating silksong bosses faster than me. Got widow in 4 tries…

I mean, you’d have to try it to judge for yourself. But I think it’s one of the best side scrollers ever made.
