Organism Editor

I'm planning to make a game called GALAXY. There will be a demo which only has the organism editor. (Think, Spore's creature editor.) since i'm a beginner, i'm going to need some help & So far, this is the current concept.

GALAXY ORGANISM EDITOR

CONTROLS: To add a part, click and drag it from the parts selection window. Tap A key for asymmetry on a selected part. Hold A key for special symmetry options. Hold CTRL to select multiple parts. click on a part to select it. Holding ALT will change the view: Mouse wheel for zooming, left click for rotating & right click for panning.

GENERAL OPTIONS: A tool for stiffening or softening up limbs, tentacles, and plant parts. From the editor, you can always save, edit or start a new organism. There will be a ring around the organism, click & drag to change the organism's size. when a part is selected, it will open a window full of options to modify the selected part. There's a tool to make parts connect to other parts to mae translucent skin(Think Bat wings.).

PART MODIFIERS: The arrow buttons are used to change the position of the part. the plus & minus buttons are used to change the size of the part. the sliders are used to change the part's appearance(Doesn't appear for the wings & fins, however.).

STRUCTURE:

BODY: everytime you start creating an organism, the game will ask you if the organism will be set to Horizontal(Perfect for animals) or Vertical(Perfect for plants). basically you start with a simple straight dotted line(Known as a bone) with two blue circles(known as points) in each end known as a line. you can add more points to make more bones & also make them curvier via bezier curve. not only it is useful to make the torso, but also the neck. you can also "split" the line. it is useful when you need to make an organism with Multiple heads. once you're done, click the tick button. this will turn the line into a "blob". you can make the parts of the blob thicker or thiner using the mouse wheel.

APPENDAGES: just like the body you use Points & Bones to make a limb but, you can change the function(Limb, branch, or tentacle). you can also make hands & feet with points & bones only you can add claws, talons, hooves, ect. when you're done, the game will ask you if you want it to be a foot, a hand, or both(Think Gorillas). To make a fin, click on the fin button, that will open the fin editor. the fin editor lets you draw the fin in a box. When you're done, the game will ask you if you want it to be translusent or not(think fish.). to make a wing, click the wing button, that will open the wing editor. it works just like the limbs & hands/feet but, you can add feathers & translusent skin(think bats.).

Yup, that was it. it might also include facial features, details, plant parts(might include fungi), colors, textures, an organ editor, a behaviour editor, a test drive mode & a gallery where you can save your organisms. Can anyone tell me how to do all this?
