- WHAT IS GEM DROP X?
- -------------------
- COMPARED TO OTHER GAMES
- -----------------------
- "Gem Drop X" is an interesting one-player puzzle game using the
- Simple DirectMedia Layer (SDL) libraries.
-
- It is a direct port of "Gem Drop," an Atari 8-bit game written in Action!
- (a very fast C- and Pascal-like compiled language for the Atari).
-
- It was originally ported to X11, using SDL for sound and music.
- Eventually, the Xlib graphics calls were removed and replaced with
- SDL calls.
-
- The concept of the game "Gem Drop" is based on an arcade game for the
- NeoGeo system called "Magical Drop III" by SNK.
-
- If you're familiar with games like Jewels, Klax, Bust-A-Move or Tetris,
- this game is similar to them all. I consider it closest to Klax.
- Some people have compared it to "Tetris meets Space Invaders."
-
- HOW IT WORKS
- ------------
- The game is played with YOU at the bottom of the screen. At the
- top is a random assortment of colored shapes ("gems"). As time
- goes on, more gems appear at the very top of the screen, pushing the
- rest downwards. The game is over when the gems reach the bottom.
-
- You'll know the gems are about to come down because a flashing light
- appears at the bottom of the screen. (Note that before the gems
- start moving in a level, you get a little breathing room. For example,
- if it typically takes 10 seconds before gems move in the level you're
- on, it'll take 20 seconds for them to START moving, then they'll drop
- every 10 seconds from then on.)
-
- It's your job to keep the screen from filling up. You do this by
- "grabbing" gems from the top of the screen, carrying them around,
- if need be, and "throwing" them back up. You automatically grab as
- many of the same gem as you can that are above you. You can carry
- as many of the same gem as you want. You know how many you're carrying
- by how many you see next to your character at the bottom of the screen.
- If you see one, you're carrying one. If you see two, you're carrying
- two. If you see three, you're carrying three OR MORE. (It doesn't
- matter how many, since the moment you throw, you'll make a match,
- explained below.)
-
- If, when you throw some gems back up, you create a "match" of 3 or more
- gems in a vertical column, they disappear (with a cool little explosion).
- At this point, if there are any "matches" of the same gem to the left or
- right of this column, they disappear too! And so on. This is great for
- cool chain-reactions! You also get more points for the more gems that
- disappear in a match. (Matching four gives as many points as matching
- three twice, for example.)
-
- LEVEL ADVANCEMENT
- -----------------
- A "match" (no matter how few (minimum of 3, of course), or how many
- gems disappear) is also known as a "line." You beat a level of the game
- (there are 20 in all) by getting enough lines. Each level requires
- you to get more lines than the last.
-
- Each level also starts out with more gems at the top of the screen,
- which means you must worry about dying more immediately!
-
- Each level is also FASTER!
-
- SPECIAL OBJECTS
- ---------------
- But, there's hope! Three special objects help you along the way.
- These special objects can't be grabbed and thrown. They are activated
- by including them as part of a match of three or more. (If you're
- carrying two gems, you can throw them on a special object to activate
- it, for example.)
-
- The objects are:
-
- * BOMB - These destroy the four gems adjacent to it. (Above,
- below, to the right, and to the left.)
-
- * CLOCK - This temporarily stops more gems from appearing on the
- screen. You'll love this one in the higher levels!
- A clock icon appears at the bottom of the screen while
- the clock is activated.
-
- * WILDCARD - (A questionmark.) This matches with all adjacent gems,
- whether or not they match the line you just created. This
- sometimes makes for AWESOME chain reactions!
-
- LEVEL 15 AND BEYOND
- -------------------
- There are 20 levels in Gem Drop X. The first 15 contain four gem
- shapes. The last five contain eight shapes (which makes it
- extremely difficult to get matches quickly). Level 15 starts a
- little slower, and with gems a little higher than level 14, to
- give you a little break. But don't get used to it!
-
- After you beat level 20, you've won! I bet you can't do it, though!
-
-
- PLAYING GEM DROP X
- ------------------
- PROGRAM OPTIONS
- ---------------
- First off, you can get a quick help page by invoking the program with
- the "--help" switch:
-
- ./gemdropx --help
-
- You can also find out what version you have with "--version":
-
- ./gemdropx --version
-
- Finally, if you want to remind yourself what command line arguments
- "Gem Drop X" accepts, use "--usage":
-
- ./gemdropx --usage
-
- If sound is enabled and you wish to disable music, use "--nomusic":
-
- ./gemdropx --nomusic
-
-
- STARTING A GAME
- ---------------
- Start a game of Gem Drop X up by typing the following at a shell
- prompt:
-
- ./gemdropx
-
- The Gem Drop X window should appear. It should be about 625 pixels
- high, so it should fit on any good display's monitor. On 800x600
- screens, you'll still be able to see everything important, if you
- position the window carefully.
-
- THE TITLE SCREEN
- ----------------
- In the title screen, you can press [SPACE] or [RETURN] to begin the
- game at the selected level (displayed at the bottom),
-
- ...or you can press [L] to change the level (between 1 and 10 or
- the highest level you've beaten, whichever is higher).
-
- ...or you can press [Q] or [ESCAPE] to quit Gem Drop X.
-
- THE GAME
- --------
- KEYBOARD
- --------
- While in the game, you can use the arrow keys in the following way:
-
- LEFT / RIGHT - Move the man left and right. (He will wrap around
- K / L at the edges of the screen.)
-
- DOWN / UP - Grab gems and throw gems.
- Z / A
-
- RETURN - Cause a row of gems to come down immediately.
-
- MOUSE
- -----
- You can also use the mouse:
-
- Clicking Left Or Right Of The Man - Moves the man left or right.
- Left-Clicking Anywhere Above The Man - Grabs gems.
- Right-Clicking Anywhere Above The Man - Throws gems.
-
- JOYSTICK
- --------
- LEFT / RIGHT - Move the man left and right.

-
- GAME CONTROLS
- -------------
- * You can abort the game by pressing [Q] or [ESCAPE].
- (It's like "game over")
-
- * You can pause the game by pressing [P] or [SPACE].
- Press a key to continue.
-
- VISUAL CUES
- -----------
- Some things to pay attention to while playing the game:
-
- * How many lines you need. How many you have made already.
- * The flashing light at the bottom of the screen - it means
- more gems are about to come down at you!
- * The look on the man's face - happy means you're doing alright;
- sad/frightened means you're getting close to losing!
