Beautiful artwork! It was a bit uninvolved to play as we just watched the plane fly along, but the artwork was so pretty that I really did enjoy just looking at that while waiting to land. I think if the other elements (wind, balloons) were animated it would add a lot to the visuals as well, plus some sound FX when hitting things might be an easy way to add a lot of enjoyment. The gameplay itself could be spiced up of course - but I saw in another comment you said it's your first time programming a game - you did a really awesome job and congratulations!!
