It's not easy to recognize our bear in an astronaut’s spacesuit, let alone identify the differences between the images of our astronaut. The game requires attention to detail, so you need to approach it with care and don’t lose patience. I wonder if it's a game for girls rather than boys. Who has the better eyesight? Who is more patient? Certainly all the children will do great and they’ll point out all the differences between the right and left image.
