Trying to unlock every Silksong ending is quite the challenge. Beyond simply fighting your way to the top of Pharloom and finishing the final boss, you'll have to complete enough side content to unlock Act 3 and brave its challenges if you want to see the game's "true" ending. And that's not even mentioning the Twisted Bud and the Act 2 ending it enables.
There's even an epilogue you can unlock, as in the first game, by completing the Passing of the Age quest, though this is a significant challenge in itself due to its final platforming section. It's also possible that there's an additional ending to the game that's linked to Steel Soul mode but that's still unclear.
