You could instantiate an interface, create a method to initialize all your types, and use string interpolation. That's just on the face of it...

The class variables should not be public. The ones that should be exposed should be wrapped in public properties.

Some of the class variables seem to only be used in local contexts. Perhaps they should be local variables instead of class variables.

Indentation and use of whitespace (both vertical and horizontal) seems to be inconsistent.

Also, isn't your code sort of mixing up responsibilities. Presumably the HUD class is responsible for updating the HUD. But why is it also responsible for updating the high score value?
