Add different cursor icons according to function

Is your feature request related to a problem? Please describe.
Sometimes it's hard for users to understand when the cursor allows them to walk vs. to select an interactable.

Describe the solution you'd like
Adding different cursos changes on hover over interactable or over the floor.

Describe alternatives you've considered
Either new icons, or a "glow" coming out of objects that can be selected.
