-------------------------------------------------

1. About

The "Return Of Dr. Destructo" is a remake of an ZX Spectrum game, "Island of Dr. Destructo" by Bulldog Software/Mastertronics.
The goal of this project is to recreate all original levels with new, better graphics, but without introducing new levels or 
gameplay elements.

In each level, you have to destroy a ship, a castle or some other structure belonging to the evil Dr. Destructo, while evading or
shooting down various aircrafts he sents after you. There is a time limit: you must complete all 21 levels in space of one week in
game time (duration of a game day in real time can be set in Gameplay Settings menu), so you have to be aggressive and take risks!

Your plane has only one bomb, and your gun is no use against well-armored targets, so you can only complete your mission by
dropping enemy planes on your target. Collisions with some enemies are harmless, but most of them will crash your plane. Finding
which is which is a part of the game experience, just like it was in 80's :)

To sink level's target, you must destroy a specific percent of its pixels near waterline. Each falling plane destroys a small
circular chunk. Level completion indicator is the red bar in lower-right corner of the screen, where level's name is displayed.

The remake features many improvements, including Casual mode, where you can continue game from any level you have already
reached with the full number of days and lives. For finishing the game in one sitting in Hardcore Mode, you get a special
achievement.
