got it first try by going for fuel/hull/drill bit and radar with spare. once you get nitro and mole, dig to the bottom, nitro across and use the mole a lot. mole rocks. also, trophies are awarded for depth and collection so if you get the mole early, you'll probably find it easier to gather the trophies. good luck =D
good idea, bad interface. the fact that you can't reposition points is pretty annoying since you have to redo all the connectors at a node if anything can't reach
