Shadow tower defense

Stepping into the emerald fantasy grassland, the obsidian spires of the Gothic castle in the distance pierce the sky, and the magic runes on the city walls rustle in the wind. As the new guardian, you will face the steel torrent of the dark army and use wisdom and strategy to weave the light barrier to protect the castle. ​
At the beginning of the game, in the meadow where the morning dew has not yet dispersed, you waved your magic wand to summon the first batch of oak arrow towers. These logs are like awakened tree people. When the bowstrings vibrate, the poisoned arrows break through the air like silver snakes, accurately piercing the throats of the goblin soldiers. When the first wave of offensives was disintegrated, the flying magic crystal fragments turned into glittering gold coins, which gathered in your palm to become the key to unlock new power. ​
As night falls, the monster wave becomes more and more turbulent. You inject gold coins into the rune array to summon the suspended crystal magic tower. The blue arcane torrent swept across the battlefield, melting the skeleton army into powder; the bronze-cast catapult roared, and the giant fireball streaked across the sky, exploding a scorching mushroom cloud in the orc phalanx. Each defense tower can unlock the ultimate move of blizzard, lightning storm, etc. by inlaying different elemental gems.
