Tips/Hints: Reset Upgrades Often
You can reset your upgrades on each stage to better allocate your stars for the upgrades you need to beat the given stage.
Don't use your specials/reinforcements sparingly: as soon as the cooldown period expires, use them.
Tips/Hints: Defeating Enemies
Different enemies need to be defeated with different approaches. If the level has a lot of armored enemies, focus on creating Mage towers. If the level has hoards of fast moving enemies, focus on Archer towers to rain down fast shots. If the level has slow moving hords of enemies, trap them with Barracks towers and then bombard them with Bomb towers.
