well so far out of the 4 flying levels i have completed two with this method, rebel attack and falcon flight i just finished not to long ago
hoth gave me some trouble and death star idk about....
its very stressful many times i have gotten to the last part without losing hearts then died just because i was to impatient.
only advice i can give is be calm, think positive, remember hearts don't vanish, just take it slow and focus, i must have done the falcon flight mission 6 times before my 7th and i didnt get hit once on my last time.
oh and as a side note... does anyone know how to change your GS in your gamercard to the left mine says 90749 but i actually have 100854.?
