The levels were created to be easily beaten so you can fly through them and watch the ads that await at the end. Half of the time in this app was spent playing and the other half was watching advertisements. Please don't support this type of game development and do not play. The game is even extremely repetitive and has no challenge. The only feeling of achievement you get from this game is when you're done watching an ad. It would be embarrassing to be a dev who worked on this game to spam ads.
