How to play Necromancer on Mac

The player controls the wizard Illuminar who attempts to grow an army of trees to attack Tetragorn the Necromancer and his evil minions who are attempting to take over a graveyard. The game is an arcade action title, but is unusual in that there are three distinct segments of gameplay, each of which affects the one following it. In the first segment, Illuminar stands fixed in the middle of the screen. Moving the joystick controls his "wisp", a magical boomerang-like device. Pressing the fire button plants a seed that will slowly grow into a tree in several stages to adulthood. Ogres appear from both sides of the screen, walking across it horizontally. If they walk over an immature tree, the tree shrinks back one stage of growth, eventually disappearing. Spiders periodically appear and move randomly about the screen. If they move over a fully grown tree it becomes poisoned, and will eventually die. Both enemies can be vanquished by touching them with the wisp, which will also cure poisoned trees. Eye-Pods containing additional seeds periodically appear and can be picked up with the wisp. The speed of the action increases continually through the level until it becomes quite hectic at the end. Every tree that survives the first level becomes Illuminar's ally in the second. Here the player enters a five-level side-view map of a crypt filled with spider eggs. Using the wisp, the player selects trees and moves them over the coffins where their roots grow into the roof of the coffins and eventually break through to crush the eggs lying below. If they take too long, the spider will hatch and attack the trees until the wisp kills them. Periodically the Hands of Fate descend from the roof, picking up anything below them and sometimes dropping prizes. The player must move through the crypt while all of this takes place, capturing question-mark prizes in order to extend ladders needed to reach lower levels. On this level, moving the joystick normally moves Illuminar, but
