I have never been good at platforming, almost gave up on getting into the main city. Luckily my partner has the skills and patience to do those pure difficult platforming challenges for me, so I managed to complete the game. Same thing with Blasphemous actually. Gorgeous game, platforming way too difficult for me.
Even he couldn’t do white palace, and I doubt I’m good enough to beat the true final boss, so I never got the good ending.
Animal well and wingspan. I think there are others too, despite trying hard to keep stuff in my wishlist instead of backlog.
Mostly my backlog comes from starting a game and then getting distracted by something else.
