Kingdom of the Wind is a fun defense game where you must defend your castle that is up in the air. You must upgrade your mana supply, upgrade units, and more in order to survive wave after wave of oncoming attackers. Each wave is harder than the last and you must survive all the days to win the game. Upgrading your mana supply is crucial as you can summon units far quicker if you have a strong mana supply. I would actually sacrifice a bit of castle life in the beginning just to upgrade my mana supply and start building units when the enemies really start piling up.

If you choose to build a bunch of crap units in the beginning, you will not have adequate mana supply at the end to upgrade and build stronger units and you will die. I’ve posted a video of someone beating the 8th and final day. Its a little different than my strategy but still works.
