The “ A Bird Chase” app has been developed for the people of every age group who have interest in playing mobile games and have courage to accept challenges. The game has total 13 windows and 2 flying birds. The game is to simply chase and touch the birds when they fly and score 100 points for every touch and if one fails to touch there is a negative marking of 25 points for every miss. For every 100 points score one gets 10 coins and for a missed touch 2 coins are deducted. The game has total 15 levels. For each level to complete, there is a time limit of 120 seconds. If one fails to complete the level, may take 3 free life and 3 more life for surrendering coins. Yes….there is a target of each level starting 1000 points for first level to 15000 points for 15th level. To make the game more interesting birds are having variable speed…if one plays fast, birds will also fly fast to a limiting speed. Some windows will open after certain level completed. Similarly second bird will come suddenly making the game more interesting. More birds means more chance to chase and touch.
