Game objective:
Protect you space stations from enemy invaders by destroying the invaders before they get to them. 

How to destroy the enemy invaders:
Destroy the invaders by creating "dense space" in their path.  Dense space is an area where you can see some color.  The enemy are destroyed when they attempt to cross a sufficiently dense area. 

How to move the "particles" that make up space:
Press and hold down the left mouse button as you drag it over an area on the screen.  This will create a path of force, or a low pressure area, along which the particles flow.  NOTE: This simulation is based on fluid dynamics, and hence the particles will not simply follow your mouse.  Part of the challange is to figure out how to control this fluid like space.  Many tricks and possibilities exist to those who can master this skill.

Game Indicators:
Level and Score are the level you are on, and your current score.  Lives indicates how many more invader to space station crashes are allowed before the game ends.  Enemy ships left indicates how many enemy ships need to be destroyed before the next level starts.  Entropy is a number that essentially describes how much of the particles are moving, and how fast.  When Entropy is 0, your sceene is at rest.   Very important to note, that when entropy is 0, your score will be incrementing continuously.  To get a high score, you will not only need to be able to destroy enemy ships, but also will need to be efficient, and have 0 entropy as much of the time as possible.

Game Scoring:
You get 50 points for each enemy invader that is destroyed.  Additionally your score will continuously count up as long as your Entropy reading is 0.  Entropy will return to 0 if you do not move particles around for a short time.  The particles will eventually come to rest, at which point your entropy will be reading 0, and you'll start getting point added to your score continuously.

Basic Behavior of Particles:
The particles are visible by the colors in the simulation space.  The highest density areas, or the areas with the most particles will be red, while the lowest density areas will be dark blue.  You need at least a light blue area in the path of the enemy invader to stop the invader.  The enemy invaders will not be affected by the dark blue ares.  All other colors will be able to destroy the enemy.  (light blue, green, yellow, red, and amber will all work)  You will get a feel for what colors represent the most density as you start playing the game.  This information will be helpful not only when trying to stop the enemy invaders, but also in mannaging resources to try to figure out where to take particles from when a new space station appears that needs protection.

When you swipe your mouse accross a part of the screen, you will create invisible force lines.  You will need to get a feel for how to control the particles using these force lines.  The particles act as a fluid would in real life, hence it's not as simple as drawing a line with a pencil.  However, once you master controlling this fluidic space, you will be able to create many scenerios to manipulate the particles in a huge variety of ways.  Once the particles set in motion, if you leave them be, they will at some point come to a stop through natural friction.  When they stop, note that your entropy reading will also go to 0. 

When particles leave the screen, they will reappear at a single point in the center of the last space station to be created.  You may notice a red point materializing in the middle of the space station.  If you hold down you left mouse button, and swip your mouse cursor over it, you'll notice it will "unfold" into a larger area.  You can, and should, use this in your favor, to transport particles quickly to any new space stations, so that you can start fending off intruding ships as soon as possible.

Pause the game any time:
Hit 'p' to pause, and 'p' again to unpause the game at any time.

Basic Strategy:
There are many ways to play this game, and there are almost an endless number of strategies that can be created by the user.  I will outline a simple, and effective strategy here.   Please look at the image on top of this page to see an example of the strategy outlined in practice.

After each level ends, a new one begins without pause.  A new space station also appears at the start of each new level, needing your proctection almost imediatelly.  One strategy in this game is to create barriers or particles around each space station.  Once the particles around the station come to a stop, you no longer need to fuss with them.  Any invader that collides with this barrier is destroyed.  To transport particles to a new space station that will be most likely exposed to enemy attack, you can move some particles off screen.  They will rematerialize in the center of the most recetly created space station.  You can tap into this supply, and use these particles to create a barrier around your newly formed space station before enemy invaders can get to it.  If there is eminent danger from enemy invaders, you can also send a stream of these particles at the enemy, and if it's dense enough, the enemy invaders will be destroyed by this stream of particles.  Remember, all of this manipulation of particles you do simply by holding down the left mouse button and swiping your mouse over an area on the screen.  Don't swipe too fast, or over to large an area at first, until you get a feel for how things work.

How to practice:
Mastering fluidic space control is key to this game.  It is also not an easy task.  Once you do master it, this game becomes very enjoyable!  To practice, while in the start screen hit 'd'. This will take you into doodle mode, where you can play around with the particles, and see the results without the pressure of the enemy invaders.
