About Castella
Castella is a tower defense roguelike in which you build a fortress and defend your castle from hordes of monsters. You construct walls to block enemy routes and protect your resources, while choosing towers and upgrades to strengthen your defenses or improve your economy.
Build your defenses
You can unlock 14 towers and over 30 unique upgrades. Your choices determine what becomes available, including ways to make your castle more resistant or improve your economy. Walls can block paths and help defend your castle and resources.
Shape the battlefield
Study the terrain to create chokeholds, gain an advantage against enemies or cut off their paths entirely. The game has two types of procedurally generated maps.
Face the enemy
There are over 17 enemy types with different objectives. Some attack your walls, while others focus on your economy; all aim to destroy your castle.
Gather resources
You mine mana, gold, iron and stone around the map to construct buildings. Enemies attack these resources when they see them, so you must keep them from getting too close.
