i found it basically impossible to jump up from the room called, "up to the attic - through the bathroom?", thus it is impossible to unlock the final level because just one level is left. :(
other than that, great game.
One thing I would reccomend for another game in this series: a bar above (or below) the enemies (especially the stronger enemies) telling you how much health they have left.
A great game, but some things that could make the game even better if you do an update or make a building rush 3:
-you should be able to build your factory anywhere in the city where there is an open space, like in the origanil building rush
-All the cars(and trucks) on the road are you and your competitors trucks. You should add some traffic as you progress and the city gets bigger
-The game shouldn't start until one factory has been placed
-some levels were there is water, you should be able to use boats
DOes it matter what direction you park in? I don't mind turning the little truck but the biggest one can't backup straight. On level 11 I had to go around the block to park int the other direction.
using spells to get bosses limbs to zero is one way to do it, but then 1 soldier needs to get there. Then the limb will not attack. defeating a bosses head will defeat the limbs to so in the scorpian battle you only have to defeat his two tiny limbs and the head. The same with the octopus
Saurian Nightscales start appearing on "The Underpass." I would recommend having barracks at the end. In fact, I would recommend barracks at the end on almost all levels after "The Underpass." (Including "The Underpass.") Then if the saurian nightscales get past the rest of your defenses, the barracks will stop them (so also have a archer tower by the barracks at the end.)
