Difficulty Curve (5pts)

[ToxicGLaDOS]

What feature should we add
The game should start off easy and get harder over time.

How should it be implemented
As time goes on a difficulty variable should tick up and the higher it is the more difficult things become (enemies spawn more, names get longer, etc.)

Additional context
Make sure to use Time.deltaTime or something else so that games running at different framerates won't be affected differently.
