I think I found both endings. Ending 1) At the second to last minigame where you collect as many coins, you exit the minigame with more than -5 lives and you will see yourself and your date under a tree during a happy, cheerful day. Ending 2) During the same minigame mentioned above, if you stay in the minigame the entire time, and obtained A LOT of skulls, you will find yourself in the hospital and your date will be next to you, weeping.

5: This one is pretty self-explanatory. The baby will demand one or more icon(s) and you will need to click them within the time on the upper right.
6: Use the mouse button to make the toddler jump. Jump over all obstacles and reach the edges of the level.
7: Click the mouse button to shoot a heart, the heart will bounce off walls. Aim for the girl in colour and don't hit anyone else.
8: Use the cursor to direct your character, collide with heads smaller than your sprite to grow. Evade heads bigger than yours.
9: Use the cursor to direct your character.
10. Spot the difference between the two globes and click it.
Feel free to play the game your own way, this is how I played it. I did not find the alternative ending.

I'm going to give some instructions for this game, (the whole game is mouse controlled)
Minigame 1: Click on the screen and the little swimmer will go in the opposite direction. Click again to make him change direction.
2: The protector will follow your cursor, you need to evade any danger that comes your way. The walls will not damage you and close to the end a big thing saying "Danger" Will be heading your way, evade this as well.
3: You need to make a uterus for the foetus, click on one of the nine squares and then on another one to make them switch places. (Hint: the foetus needs to be in the middle)
4: Click the mouse button when the indicator is in the yellow/orange/red area, you will need to do this twice for each colour. After this is done you will need to press the grey button several times.
