Necromancy!

In Necromancy! you play as a necromancer who has been cornered by an angry mob of the living. The necromancer cannot attack, so you must raise and control an undead horde to protect yourself. When your horde kills one of your attackers, you can raise them as a new undead to add to your horde! As your horde grows, so will the waves of enemies attacking you. Survive as long as you can!
