Funny Puzzle

I had this game on my old phone. It was a good game so I thought I would revisit it. I understand and don't mind the fact that adds are part of a free game and that this is how the game maker makes their money, but come on a little bit of common sense! Why would you put the advert bar over the top of the part selection bar in the game? This results in a unplayable game! Did anyone think of checking the game works, ie actually try to play the game? Why not have the advert pop up after every level ?
