It's a wonderful game for increasing concentration power and individual reflex. The player has to focus on the ball and direct it toward the stairs. The colour of the stairs sometimes resembles the background but if you focus enough you can find the difference and cross that huddle easily. Time after time the size of the stairs reduces and requires quick reflex to jump toward next stair. These challenges improve the human ability of colour detection and reflex time. A Fun way of improving these abilities is with this game. You surely find improvement after a week of playing this game. Take this game as an exercise, not as a game.
