How can I mimic a Camera from a game to my project?

Hi! Interessting Question: Let's analyse this a bit: Before: I do not know or played that game.

It seems like you play the most of the game with a Static Camera which serves in a simple "2d"isch sidescroller. https://i.imgur.com/iFuh1v9.jpg

And then there are these transition Scenes: Where the player changes direction from one "2d"isch direction into another. In this cases, the camera moves not only with the character but on it's own to smoothly transition into the next orientation. https://i.imgur.com/i1B3dEd.jpg

I would souggest to start with a simple character which can move left, right, up and down and is constrainted from it's enviroment. Then I would Implement, other directions of long sections an place a kind of marker which indicates the camera to turn, to match the rotation of the next marker like here: https://youtu.be/lzNzwAqqHPs?t=3699

I think that would represent the jist of the game. Have fun and keep me posted!
