In the early days of the game there's not a huge amount of strategy to speak of. Spamming the production of bog-standard warriors, and unleashing your magical and healing spells whenever they become available will get you through the first dozen or so levels rather handsomely.
In later levels though it becomes critical to manage your army much more carefully: there are molten-dripping towers that benefit from an archery attack, rather than having your ground units get burned to a crisp in the process of taking it down.
The various traps, which can initially be ignored as you spam the heal button, become denser, forcing you to disable them at your earliest opportunity.
