(Suggestion) Speed up the gameplay

[profesor80]

Speed up the gameplay once the player reaches every 100 scores.

My suggestion is to have 2 different speeds. One for the player and everything that comes with him (ex. bullets) and one for the "rest of the world" (map, enemies etc.).
That way not only the player can play fast, but we also can increment the "slowness" of the rest of the world as game time progresses making it harder and harder.
