Just in case, here's all the answers if you want to get the (not even arousing) ending without making your head explode.
1. Homer.
2. Co2, Water, and salt.
3. Hello Kitty.
4. Einstein.

For some reason, I got all of these things right at the first time. Does this mean my brain actually works?

Anyways, the girl's style is horrible, the animation is atrocious, the background is from a Windows XP wallpaper, and even the text looks like it came from the Notepad shortcut in your PC. Wasn't even worth the ending, plus, it only looks arousing for a three year old. It's a wonder why this game is still standing.

The first question made me consider the education I was given, as I had heard glimpses of these names before but could not place their exact works alongside them.
The next questions made me consider suicide.

i like this game but its kinda short and it needs more questions and plus its about education not her naked body

Since this is old, i'll give ya this much.
.....Extra half-star for Hello Kitty.
