Preparing for release on Google Play

Made a lot of changes to prepare the game for release on Google Play.

List of changes:

• Added a button for calling the side menu with portals.
• Rebalance prices and worker productivity.
• Added a button to exit the game to the right of the bar table (necessary for better operation of the save system for Android).
• Reduced productivity of workers when the player is not in the game.
• Added autosaves every minute (does not work for HTML).
• Now the level of the cafe also affects the productivity of workers.
• Fixed some performance bugs.

The Android and HTML version have been updated to the test version of Google Play.
