i havent used human troops for a while, i like my ancient troops, but there really are no cheats or glitches on that game, i couldnt even use cheat engine too hack it so i needed too beat it legit XD, also for some of the 'perfect' levels, you need too take a mobile army, witch means.. constantly attack, dont risk waiting for them too attack dont take a turn too regroup just keep attacking.
for level 3 take his drunkeness's advice, ill give some advice of my own for lvl 4(breakout)
-Never waste a turn fortifying or cultivating, only make crusaders and constantly attack. What you do in the fights is the following.
the first fight is against a base with only 3 hp, all you need too do is send crusaders(bottom middle top) quickly and ull win withought any loses, second level is the same exept it has 4 hp, what u do is send the three crusaders take it down too 1 hp, then wait for them too send a charge unit of their own(very fast one) and the second it hits ur base u send a crusader from there and ull win with only loosing 1 life. do the same for every single lvl with 4 hp. and do the same against the enemys base since it has 5 hp ull need too do it once more.
