help a new player...
I just got the game last Friday, and I've spent the last day or so trying in vain to beat the tank in the volcano level (the boss you meet after getting the second ship and the beam gun). I've discovered that it is vulnerable from the back, but I'm having problems staying alive long enough to get in more than one or two hits before either it shoots me or I'm overwhelmed by the mines. Are there any tricks to it? Thanks!
