Best driving modes are Extreme and Defensive. Go Extreme early on, your guy is faster AND more manuverable (yes, he will crash less on extreme than on normal). Go on Defensive if you are way ahead, the other guys are dead, or are low on fuel.
You can never run out of money for training - get at least 100 money, train, go to menu, then play and continue. You have your money and you keep the stat.
the DRAGONS are steamrolling everything. I mean, they're flying, evasive, high armored, have a fat long ranged penetrating laser and a huge-ass-explosive rocket.
I am stuck on the 3rd or 4th level before the last on the map. No destroyers (no plasma cannon), and the enemy has a huge fleet and a ton of specials. I think I should replay the level a few times to save up 4-5k for EMP and air strikes/rockets if I am to have a chance, but it's boring. Overall quite enjoyable 3/5
Try to stop the dots. Make a circle while holding the LMB. Move a bit to the left or the right to feel which way the circle is shrinking. Shrink it so that it inverts, the direction of rotation of the dots will change. If you stop at the right time, you can almost keep them in place.
