On every level you should use the primary weapon (unltd ammo) nonstop and focus your efforts on dodging ships and projectiles. Also you should stay near the bottom of the screen. Use your secondary weapons on big enemies (or groups with the lighting) and be sure to collect as many coins as you can, its o.k. to use the pull coins move, its really helpful. Dont risk your ships with daredevil antics :( and save your bombs for the boss. Remember these things and you should be successful, dont forget to scan bosses for weaknesses too!
