I can recommend Halls of Torment if you like games similar to Vampire Survivors, it has more of a Diablo feel and there are “secrets” on the map that can help you with the boss.

I turned off auto-rotate, so when I rotate the phone I get a symbol in the top right corner to notify me that the screen rotation is locked and I just press that and the screen rotates to the current position. I use a Galaxy Fold 5.

I couldn’t find it mentioned already, but I really loved Vagante. https://store.steampowered.com/app/323220/Vagante/
