Lich

Made in one week for the "Week of Awesome III" Game Jam. The theme of the game jam was "Death is Useful".

You are a Necromancer Lich, with the ability to turn your fallen foes into skeletons, and to return to life after you die. While dead, you can pick up mana to boost your magic power and to progress to the next stage.

The tutorial explains how to play, but here are controls for reference:
WASD to Move
Mouse to Aim
Left Click to attack. Hold and Release to charge your magic attack
Right Hold and Release to Raise Dead. (Or right-click if you have mana)
Spacebar to return to life.
