If your still on normal, and need quick money, just go back to lvl 10 and keep doing it for an easy 20k eachtime. if your strong enough, killing the dragon will take little time, and earn ya 10k
if your going for time stopper, another hint is too pass a level, and then come back to it later. you will have alot more stronger units and spells. another tip is to target the buildings with your heros, and allow any units (skels and orcs and zombies) to pick off the population on auto roam. this makes beating the time alot easier. hope this helps XD
after character creation, the tips pop up, and when closed it just shows a gray screen with the menu images but i'm unable to click anything, can any1 help?
