Tutorials to build 2.5d game like "Project Octopath Traveler"?

Hi everyone.

I’m looking for any kind of resources, especially tutorials to develop a Project Octopath Traveler - like game in 2.5d.

So far I found a lot of stuff on 2D development - pixel art, there’s even the side-scroller project that can be used in UE. And of course I watched a lot of tutorials on the usual 3D game as well.

Now what I meant by a 2.5d game is where the characters are in 2D (pixel art) but the environment in 3D in some areas so the player can move in any direction (not only right or left). The Project Octopath Traveler is an excellent example.

Could you please give me some tips on how I should start to build such game? I guess what would help me the most is to find a professional tutorial with the aim of building such 2.5d game. If there is any, I would gladly pay to get it.

Thanks

This video shows the making of Dungeon of the Endless, which is also a wonderful 2.5d game.
Although it is made by unity, the concept is the same.
