 \| 2. Object of the Game |/
  +=======================+

 In Invalid Tangram DE, you are fighting ever-more-powerful waves of enemy ships.
 You have a primary gun at the front of your craft, but can get powerups to make it
 more powerful, faster, and shoot in multiple directions at once.  The end of the 
 game is determined by time, not health: as you are hit, you lose time, but powerups
 regenerate some of your time.  When each ship dies, it turns into one of three types
 of block that falls to the bottom of the screen.  In order to get a powerup, hold
 the notch in the bottom of your ship over a group of two or more touching blocks and
 press the absorb key ([ALPHA]).  The more blocks you get, the more power you earn.
 The powerups slowly drain as time progresses; the amount of power you have is indicated
 by the three bars in upper left.  Try to stay alive as long as possible and survive as
 many waves as possible to get a high score.  Your score is shown in upper left, while
 the time left is shown in upper right.  Additions or subtractions to/from the score are
 shown in smaller font underneath the time left.

 Invalid Tangram has two difficulty levels, Easy and Hard.  The difference between the
 two is how block absorption rules are constructed.  In the Easy mode, you can absorb
 any group of two or more blocks at any time to gain powerups.  In Hard mode, however,
 you can still absorb groups of two or more blocks to power up, but you can ONLY absorb
 blocks of a specific type when your powerup bar for that type of block is EMPTY.  This
 makes the game substantially more challenging, because you can't keep getting combos
 to top up already powerful powerups.
