*** About ***

Zmiy is a snake game designed for DOS and 8086/8088 processors. It's very
small and pretty fast. Zmiy simulates graphics using a 80x50 text mode.


*** Controls ***

Zmiy is entirely controlled via the keyboard. Key bindings are listed below:
 Arrows - Change the snake's direction
 Escape - Quit the game
 Enter  - Pause the game (the 'P' key does the same)


*** Scoring rules, lives & speed ***

The scoring rules are simple: for every collected item, you get 10 points.
When you hit an obstacle, you die. The number of lifes you have depends on how
much points you earned. A life costs 100 points. If, at the time of dying, you
had enough points, then 100 points are subtracted from your score, and you can
replay on the same level. If you don't had enough points, the game is over.
The speed of the game is closely linked to your score. A bigger score means a
higher speed. If your score decreases (because you loose lifes), the speed
will slow down. Note, that there is no speed change during the gameplay. The
speed is computed at the begin of every level.


*** Hardware timing ***

As for most games, the gameplay quality of Zmiy is greatly impacted by the
accuracy of how the game handle timing. The timing mechanism is configurable,
because on different platforms timers can behave differently. If you feel the
game is laggy, or behaves erratically, you might want to try an alternative
timing mechanism.
See the help of Zmiy for more information (zmiy /?).


*** System requirements ***

Zmiy have very low requirements, but still, it needs at least:
 - an 8088/8086 CPU,
 - a VGA graphic card,
 - MS-DOS 2.0+ (or compatible),
 - 20K of free conventional memory.


*** Building from source ***

The Zmiy game is written in ANSI C (89). It has been compiled using the
Borland Turbo C 2.01 compiler. A makefile is provided to automatize the
entire build process.
