it's a good game, but to much clicking involved - click on unit hit upgrade - click back on unit hit upgrade - click back on unit etc etc, how about click on unit and then upgrade 5 times...
LIMITED MONEY LEVEL CAN BE BEATEN YOU NEED TO GO STRAIGHT FOR CAPTAINS + PRIESTS TO HEAL...OOPS CAPS.....don't wate money on anything else, upgrade prist and captain and you'll finish withy 300+gold
you cannot kill anything until you get the lightening - you need the parachute, climb up to the top of the pillar and use the parachute to fly right to reach the realm up in the air
