2,5 D adventure

Is it possible to create a 2,5 D point and klick adventure game with an inventory, combination riddles and so on (like black mirror)?

Sure. It’ll be a lot of work, but any worthwhile project is.

You can even add another 0.5D to make it 3D.

I’m a bit sceptical on this one, until I see some solid evidence on this I won’t have any of it.

The Monkey Island 5 Demo?
