First and foremost thank you for a great show!
And thank you for featuring my game!
A few pointers - to complete a level you need to have +1000 points before time runs out (a voice is saying 3 minutes... 2 minutes... 1 minute to let you). You actually got very close ;-)
Second point - every action costs fuel - I saw that from the second time you played you had the beamer on the whole time - that costs a lot of fuel and should only be used shortly when directly over a cow. The second the cow gets locked-in by the beam you can release the fire button.
Third - The one who controls the gun also controls the shield. By pressing the joystick up, you engage the shield so that no bullets can harm you - however - shield cost fuel - so use only short bursts.
With these hints - you should be able to get to the next level - featuring submarines! Watch out - that level is tricky, but there is a strategy that helps you if you can figure it out. Next level is Panzer train - It helps a lot if you've watched a movie whose title rimes with 'dope'.
Again, thank you for a great show - it also allowed me to dust off my german - which is where I will have my summer vacation :-)
