For the last level just make 2 mortars. Once they have full ammo move them off to the sides to take care of the creeper. Once they're out, bring em back. Rinse and repeat. Should be fine till you can make a drone or 2.
For battles 7+ have maxed out mana and make 10 or so pallys and send some seige units along behind them. This should kill the castle before the super wave can get past your pallys. If not just wait for them to advance within your towers range and send more knights to stall them while you shoot them with arrows.
For level 16. Have maxed castle and tower upgrades for the specials. When he comes out spam hobbits and use your titan and specials whenever you can. Hobbits prevent him from advancing too far. Also when the range units come in range of your arrows, destroy them first.
To kill the super wave just let your troops die so they can advance far enough for you to shoot them. Then send in another wave of pallys to stall/kill them as you shoot your arrows.

Get at least level 3 barracks and save up enough mana to get 3-5 pallys and you should be able to beat level 6. Either that or send 15 or so warriors 10 or so archers and a couple catapults.
