A fun and easy game for all ages. The Mir aliens have come to Earth along with the Groog. Do they come in peace? Mastering this game seems easy but to score a perfect game is puzzling unless you are the clever one. This game carries a message of peace and the only violence in this game is bopping the aliens on the head. No one dies and no gore. Sounds best with earbuds and is a great game for zoning out and also has a lesson for kids. Game has multiple end game messages based on your performance. Info window has settings for difficulty level and time period (1 to 10 minutes). Less
