• Made the game playable for guest accounts
• Condensed the control buttons into a menu and added an "Exit game" button
• Store sound & alert preferences locally

• Fixed enemies regaining abilities when they shouldn't
• Show a warning before leaving a game
• Will no longer try to draw map previews when data is missing
• Close tower menus when dragging a tower
• Changed how tower menu position is decided
