okay really you want to aim for 2 badges at once speed and height , distance and time.
i did it in 20 days with everything maxed its easy
just fly up with resistance about 15% until rockets run out then dive until it hits 0% resistance and you should dive to about 4200 then just float along the water staying about .4 of the water. i finished going 160 at 6000
nice game , its ver different and has a interesting story. 4/5, would have got 5/5 but i kinda got sick of the music after a while , maybe add a mute button or turn down controls??
