Hello Snapshot! Here are a few potential tools and tutorials that may help you reach that goal:
- Articy: https://www.fab.com/listings/e9edb068-c115-4fb0-a7f3-d17460b5dd28 While this seems to be more inline with a narrative/visual novel type game, you can probably use several aspects of this tool for a point and click game as well.
- Point and click multi-interaction: Point and Click Multi-Interaction | Community tutorial this is a community tutorial that will help you a lot in your goal I believe.
- Unreal engine tutorial: https://www.youtube.com/watch?v=rt0ojxt6oJQ this is for UE4 but the overall information should still be useful for you to adapt into UE5.
I hope those help and good luck with your project!
