From Ian MacLarty:
*** Now with Retina Display graphics ***Tappysack is a simple game where your goal is to keep your hacky sack in the air by tapping it. The longer it stays up the more colorful and alive the background becomes. Music plays, bees start buzzing around and butterflies flutter by. Eventually the sun sets and crickets and fireflies emerge. Drop your ball, and the background reverts back to its initial black and white state.Features: - Natural feeling ball physics - Beautiful hand painted retina display graphics - Relaxing background music - "Normal", "Hard", "Zen" and "Walls" modes - Multiple ball designs - Game Center leaderboards
