The basic idea

You are commander of the night watch of the city. Undead are attacking from the right of the screen. Your city is on the left. Stop them from reaching the left side. You can build defense structures like walls and traps, recruit soldiers to defend your side and employ mages to cast spells on the undead forces.

Undeads attack in waves. Each wave starts after a fixed time. The undead army get progressively stronger on each wave. Each level last a specified amount of waves (like 4 to 5 waves).
