Guys to earn the last medium badge right when you lift off go fast fast but
leave a little fuel left and keep moving up and down up and down and when you reach the 5000ft mark use the rest of fuel and just keep going up and down
I got 3000 on first try I really loved the different music for the different 'power ups' I certainly loved the guy that said "You go to hell you go to hell and die!"
Tip for beating all 9 levels: Focus on Magic, Attack, and Defense don't worry about range unless you have a bunch of bullets and a musket and catapult. You need 2 breastplate to max out your defense. 2 battle axes to max out your attack. For magic get the big bottles of magic and the medium but if you don't get any medium size bottles and only large and small take them!
