Mario & Luigi RPG style top-down platforming

How do I…

I am trying to recreate the platforming seen in the top-down Mario & Luigi RPG games like Superstar Saga on the GBA. It is top-down but you can jump onto platforms and hit blocks to get items. I think I would have to “fake” 3D to recreate this but I could just be overcomplicating it so any help is appreciated.

What is the expected result

Mario & Luigi is in a top-down perspective and able to platform on platforms of varying height.

What is the actual result

I haven’t tried making it in gdevelop because I’m not sure how to implement it, or even if it is possible.

Project files (optional)

My project is just a scene (called “Game Scene”) that loads an empty external layout (called “World Map”) in the scene beginning.
