A very creative, intriguing and beautiful game!
I am not really sure what the story is all about. To me, it seems like it is about a love, perhaps a forbidden love. The woman knows that it is not right, but she goes with it anyway. Or possibly rape is involved and the man forces her to bear children. It also seems that the idea of a cycle is important, from the very last few lines. Whatever this is about, it is a very emotional and though-provoking piece. I remember playing it when it was first submitted, but never finished. Now I have played through three times in a row, just to get a grasp on the story. I think the meaning is completely subjective and it means to you whatever you want it to mean.
For anyone stuck on specific levels:
1 - Move the mouse back and forth to move the sperm to the egg, once it is in a bit, the game will take over and move the sperm where it needs to be.
2 - Move the mouse around to separate the balls into three homogeneous (same) groups. They have a tendency to move to the correct group, so just keep moving them around until you get them grouped. You have to have the three groups completely separate from each other to finish the level.
3 - Rotate the mouse around the ball to move it left or right. The sperm things will move you up, but you want to go to the bottom. Hugging a wall helps as the sperm generally appear from the middle and will not be able to knock you upwards in time.
4 - Guide the tentacle with your mouse and capture the balls and move them into the thing at the bottom. The shrimp will carry them away, but you can let the first two take off and should have enough time to get what you need before they come back.
5 - This one is a little more involved. Placing the mouse over one of the ovaries at the sides will rotate the guy in the top screen. Placing it over the ribbed object across the bottom will move him forward. The goal is to get as many of the eggs into the uterus as you can (I think you need 4 or 5). Once you get close to a group of them, rotate the guy so his tentacles are over them and it will suck them in. You have to be fast because they do not last too long in the uterus. Placing the mouse over the uterus makes it jiggle, but I do not know that this does anything.
6 - Aim at the other thing floating around and the game will shoot at him for you. Just keep chasing him and he will eventually slow down so you can catch up and just stay next to him until the level ends.
7 - All you have to do really is let the game expel all the stuff and it is over. You can rotate around, but I do not know that this helps at all. Just be sure to let it float down to the bottom so you can see the cool water effects. Also do not go too crazy rotating the mouse around as you might skip the first part of the ending.
Hope this helped anyone that may have been stuck, and have fun figuring out what this all means to you personally!
