About
=====

This is my entry for ciw1973's "Space Invaders 
resource files" compo held in the www.freebasic.net 
forum from Nov 1st till Nov 19th of 2007.

Invatris is a Super Tetris (1991) clone (also 
including a classic Tetris mode), featuring the 
graphics and sound from the original Space Invaders.

This is an incomplete version, but only few nitpicks 
can be expected in the final version.

During development an action part of the game happening 
between Super Tetris levels was dropped for good.


Gameplay
========

Controls are arrow keys. Left/right move, up 
rotates, down speeds-up the dropping.

In Super Tetris you need to clear all lines 
below the DEMARCATION LINE (yellow color) to win
a level. If you clear lines below the demarcation
line, blocks push up (to cover the cleared space). 
If you clear lines above the demarcation line, 
blocks push down like in classic Tetris. The main 
strategy is to keep the least amount of blocks 
above the demarcation line, and especially
above empty space below the demarcation line.

Use seldom appearing bombs to destroy blocks that
are covering empty space.

The game speeds-up after every few cleared lines.

There are 5 levels in Super Tetris mode.
There are 11 levels in the classic Tetris mode and
you can't win in this mode (you play it until
losing the game). I recommend playing with transparent
playfield in the classic Tetris mode.

Scoring works like this.

For each cleared line you get 100 + cleared_line * 50

So if you clear 2 lines you get:

100 + 50  for line 1
100 + 100 for line 2
