flappy jet - iron dragon named

You are small (but big!) Dear non-flying dragon who wants to travel on the ground! And you can not fly, you use a jet pack for this! But because of your low budget (you are a dragon after all!), Your wings are of very poor quality and can only be used in very short series.
In other words, you must pass through obstacles and progress! Do your best to avoid obstacles and go as far as possible
