You could try [campfire](https://www.campfiretechnology.com/), it's marketed as a worldbuilding and planning tool. I've also looked at [Scrivener](https://www.literatureandlatte.com/scrivener/overview), which may have a more familiar interface to that of PowerPoint. [WorldAnvil](https://www.worldanvil.com/author) is another tool, although this one may or may not handle scene management as easily (I've not used this one extensively enough to figure that out yet), WorldAnvil will allow you to build a sort of Wiki for your novel and create links between characters, locations, events and all sorts of other details.
