Saftorio's Pizza v0.0.0.3 (Prototype)

A small update post-stream!

This adds the following features:

• Music continues to play while game is "paused"
• Fixed an issue where hitboxes were over-sized.
• Options menu is accessible from the title screen and the pause menu (accessible in-game using ESC). Current options are fullscreen toggle and game volume.
• Options selected should persist through game runs.
• Pizza projectiles now have shadows.
• Under the hood (not implemented in the stage yet). AlienSpawner can now be configured to spawn aliens of different colors.
• Pressing ESC on the pause screen will return to the game.
• General UX styling improvements.
