build roads without spending stones
Place a building (WatchTower preferably) and wait till worker flattens
the terrain for it. Once it's done - demolish the Tower. You'll have one
block of road for free . To speed things up - place dozen of towers at
once. Note: roads built by this method are not visible on mini-map.
removing roads
There is no way in K&M to destroy a road tile unless you build a house
on it and demolish it. Thus if you seriously suffer from too many roads
and too few space for fields this trick may come in hand
get rid of trees that block your building plans
Place a building right below the tree that you want to got rid of. Wait
till worker flattens terrain and tree will disappear. Demolish the
building area. Note: while getting rid of the tree you get one road
block which will interfere with building corn/wine fields.
flatten terrain for building
Sometimes terrain is very unflat and you can't build a house on it. It
can be flattened a bit if you build a piece of road over it. It may
require to build several blocks of road to flat the terrain good enough.
optimizing buildings construction by laborers
You probably noticed that after house is built laborers keep building it
for a few more seconds (and those heading to construction site keep
walking towards already built house and even put efforts into it). You
can save that time by enabling/disabling repair of that house. Laborers
stop building it immediately and may continue with other buildings of
yours
speed up building destruction by army
Order your solders to attack an enemy building. Wait till they surround
it and start destroying it separately from one another. Order to attack
building once more and all your soldiers will hit it at once. Now wait
till actual hit and few more frames and order to attack again. Repeat
attack command after every hit. You can even catch a certain rhythm.
Thus you will speed up destroying of a building
speed up archers attack
Same as with previous trick. Though with archers you can also rain your
enemies with arrows/bolts. Repeat attack command after arrows/bolts
leave bows/arbalets. Thus increasing shooting speed
