Defence to death is a tower-defence game about defending your castle from monsters. Its compact design puts tower placement and hands-on combat alongside resource gathering, asking players to balance protection with ways to earn and spend money.
Players can build, upgrade and sell towers, with tower upgrades purchased through the shop. The game also lets you earn money by clicking on a mine, while clicking enemies directly deals damage. These actions give the defence a more active feel than relying on towers alone.
The shop is essential to improving towers: the game notes that upgrades cannot be made without buying them there. That creates a straightforward loop of collecting money, investing in tower strength and responding to incoming enemies. Its mix of tower management, mine clicking and direct attacks is the defining feature of this small-scale castle defence.
