To navigate through, watch out for the tricky gravity with pressing space bar to add thrust to your blimp and release it before hitting the top and don't forget to collect fuel power-ups to not to get out of petrol. That's all you need to do.
Looking for a good score? While trying to fly as straight as possible is a bit easier, it will not result in such a high score. Try to do some daring manouvers to receive some extra distance.
Good Luck!
Blimp is down!
