2D/3D ball game (first time making a game)

Questions
1

Basically, I want an arena which will be an oval shape and I want players to roll their balls around inside of the arena.

Will basically be a destruction derby and maybe pushing other balls out of the arena.

I am wondering is it possible to have 2D ball rolling physics from a top down perspective? And if so can the arena have multiple levels sort of like a bowl?

Thanks

Something like Marble madness I am mostly interested in which seems like a combination of 3D/2D https://www.youtube.com/watch?v=-_rkCXLEGXY

Yes, you can do it with Defold

2D + 3D

Thanks for the response, I am basically trying to do pool ball or pinball style balls with curved environment or ramps/objects they can bump into.

I am also wondering is it possible to create a transparent ball with objects inside of it?
