Are you really using Godot 3.2.1? If so, I wonder why you’re using such an old version?

Not sure what info you’re looking at. According to this article, it was released in March of 2020.

The current release is 3.5.1. Download from here (if you want).

if Input.is_action_pressed("up"):
    velocity -= speed

needs to be:

if Input.is_action_pressed("up"):
    velocity.y -= speed

you can multiply and divide vectors by scalars, but you cannot add or subtract them.
