Growing Dogs

What a beautiful day to take a stroll in the park. Our dogs are also happily walking with us. We attack and collect the people we come across on the way.
When we touch the screen, they start to run and attack. With every character we collect, the number of dogs increases. As the number collected increases, the dogs begin to change and our outing becomes more enjoyable.
You have to watch out for the obstacles on the way. If the dogs you collect hit those obstacles, their numbers will decrease. Collect as many dogs as you can to the forest at the end of the level. Release them into the forest. Wave after them and win the game!
