Flapster Flight
Initial prompt
Modern App Store icon, high definition, square with rounded corners, for a game titled "Flapster Flight" and with the description "A tap-to-play side-scroller where you control a bird flying through obstacle pipes. Tap to flap and keep the bird airborne while avoiding collisions with pipes and the ground. Simple to learn but challenging to master, with each successful pipe passage earning you points.". No text on icon!
