I think this great game can be a multi-generational game. That's why you might think about introducing the option of leaving messages on some levels. If my family plays it for years and could leave a message and text then in time people from the family could get to the information left by their predecessors.
Example - my dad is dead four years ago and he played the game for years he could leave me some information - I think it would strengthen the position of the game in the world. Regards Robert
