Firebird is one of a few companies that produce low-cost software. You should of course remember that you only get what you pay for. I would imagine that Estra is a game for the younger members of the family. The basic idea is simple and playing it is not complicated in any way.
The object is to collect the 24 pieces of a statue and take them to the temple in the middle of the screen. Only one piece may be transported at a time. As each portion of the statue has been deposited in the temple it is put into its correct position by the computer.
As in most games of this type there are a few meanies wandering about that will kill you if given the chance. Some of them are destructible by you although others are not.
The instructions for playing the game are given in the program. Although they are good I always like to see them printed on the inlay card as well - just in case I want to look them up in the middle of a game. Either a joystick or the keyboard may be used to play, and a pause feature is included.
The graphics and sound are very straightforward and do not hold any fantastic secrets. I would consider the game to be good value for money but not all that hot when compared with the more expensive games.
