Release notes
-------------
This is the first released version of Pentis, a simple game based
upon the classic puzzle game Tetris, with the difference its name
implies.

This product is at an early stage of development.  The game is fully
playable, but for the time being lacks such features as a high
score table, on-screen help, etc.

Binary and source distributions are available:

Instructions
------------
Double-click in the window, or press Enter, to start the game.

The game is played using the numeric keypad with Num Lock switched
on.  The controls are:

7 - rotate anti-clockwise
9 - rotate clockwise
4 - move left
6 - move right
2 - move down
0 - drop
P - pause


In this implementation, if you drop a piece using '0', it is not
actually settled until the next tick.  Thus it is possible to drop a
piece and then slide it under another.

The scoring system
~~~~~~~~~~~~~~~~~~
Dropping a piece with '0' scores the number of squares that the piece
fell by this action.

Completing N lines at once scores 100 * N * N * (L + 1), where L is
the number of the current level.


Building from sources
---------------------
The source is designed to be compiled using Digital Mars D 0.126 or
above.  It also requires SDWF 0.5a or above.
