Premium Upgrade

The Premium Upgrade is an upgrade for Smash Hit that unlocks new features

Features
The upgrade adds the following features:
 * Game Modes: Adds different ways to play Smash Hit, such as an easier mode, a harder mode, and two multiplayer modes.
 * Mayhem Mode: Makes the game harder by adding more obstacles, less crystals, and bosses.
 * This game mode changes the layout a bit, as the Checkpoint 11 Automatic Door is moved to the end of the boss stage.
 * Zen Mode: Endless meditation. It also uses Infinite Balls as Power Ups, and acts like meditation.
 * Training Mode: Acts as target practice and decreases the number of obstacles.
 * Local Multiplayer Modes: Suited for 2 players:
 * Versus Mode
 * Co-Op
 * Achievements: Connects to Google Play (Android) or Game Center (Apple) to give achievements for their work.
 * Statistics: Adds statistics and shows players their progress.
 * Restart from Checkpoints: Allows players to restart with the same multiball status, and balls, from when they entered.
 * Cloud Saves: Allows the game to save to the cloud so you can continue progress (same balls, statistics, etc.) on other devices.
