Thrax Lair

_Thrax Lair_ is a vertical shoot’em-up, that kind of resembles River Raid.

Thrax, insect-like, cave-dwelling creatures, have always stolen the eggs from
tarps and their offsprings. Tarps are pterodactyl-size creatures that have the
ability to shoot electro-chemical energy through its eyes. This is a
recreation of a tarp raid on a thrax lair.

You control up to 3 tarps and for every 10,000 points you score you awarded
with an extra tarp. The tarp can fire energy bursts from its eyes in the front
direction, left, right, and the diagonal front directions. You score points by
shooting enemies. The faster you fly the more points you get. Depending on the
kind of thrax you are awarded with more or less points:

Workers will give you 30 victory points. Soldiers will give you 75 victory
points. Stingers will give you 150 victory points. Monitors will give you 350
victory points. To kill a Monitor or Stinger you have to hit the eyes.
