Ugh DOS Game Online

His girlfriend had always had great expectations and one day, by an incredible chance an apple which has fallen right down our caveman's head creates a thought of an aircraft that he can use to earn money. So he makes the machine and uses it for the transport--for picking the other cave friends up and dropping them to their desired destinations. But it won't be an easy task; first of all he has 69 levels to pass each must be finished in a limited time and his only weapon for protecting himself from birds, rhinos and dinos will be a cute rock. Flying too fast won't be good for him either because he can crash into stony places. So help him out!
