Is it possible to control the main ship with mouse? Rather than just the 2 player one? My big fingers aren't much use at steering around with the arrow keys! 3/5 for now, 5/5 if I can use my mouse!
xshamanc is totally right, i managed to beat it in the end with engines at about 5, shield about 60, and weapons at about 130. so just don't waste ether on engines and you'll get there in the end. oh and "continue" comes in pretty handy too :)
