Cleaned up the code a bunch, since it was a pile of spaghetti code. Now it's much more reasonable to maintain and add too.

Speaking of which, I've added mines to the game, you have to avoid them or your ship will explode.

The mines slowly rotate in place to make them easier to see for the player since they might be easily missed, they look pretty cool tbh.

Each map contains around 200 of them to avoid, spaced around 350 pixels apart from each other
