At a low level, get your speed to 1000. After that you're pretty much good. Level up speed every once and awhile, but as a rogue it won't matter too much. After you get 1000 speed, just spam attack level up. Keep using leech, and stun. Against the bosses, you should be mostly using stun, and wound.
GUIDE FOR NECROMANCER:
Here is all you need to do. Build up your rage during the start of the fight. Then as you progress, use wound, then stun. Whenever he summons, his wound is cured, so you won't ot keep him stunned as long as possible. Hope this helps!
Welll.... Crap.... I sunk every plane so far, then I hit the last stealth plane. As soon as he was about to hit the water... BAM! Game over. Final score: 1,443,785. ASUJFHUFSAHGUDHGU
Tips for beating the giant crab:
First, attack the upper large claw, and destroy it.
Then attack the middle claw, on the upper side.
Destroy the lower middle claw. Send your troops from the lower half of the screen, to the top. This will increase survival rate.
Keep sending your troops from lower buildings, to the higher buildings, and attack the head. If you have sent all your troops to the top, the lower large claw should not even hurt them.
