Yes, it's "Fury of the Furries". One of the best platformer ever made :) Your turn.

And BTW: Trine is often compared to The Lost Vikings which I find weird - you have all three Vikings on the same level all the time while you switch characters in Trine. In Fury of the Furries you do it too :)

Mother nature is after me, all animals hates me, so that's make me a serial animal killer. The one man who found me very attractive was killed in the process. I have zero to none emotions and don't afraid of anything.

Can you describe the main character?

Long legged busty woman (typical)

Funny, when I rode your first post I thought about Tomb Raider, because she killed a lot of animals since the very beginning of the first game, until the last one...

What kind of weapons does the main character use?

You guessed right, it's Tomb Raider (1996)

Pair for pistols with unlimited ammo apparently ;)

Just in case, it's your turn afterall

Funny, I thought about TR but decided it didn't fit to your description. Now I'm not sure why I thought so? ;P

It is your turn monsieur

I am really sorry for the delay I spent the entire yesterday in a restaurant... And as Ghorpm I thought being wrong with my Tomb Raider idea...

So:

I hear a voice in my head, yet I hear voices in other's heads too.
Male or female, I am human yet I am not.

I remind you english is not my native language, hope it's ok but tell me if my sentence are incomprehensibles!!

Are you talking about yourself here, or is this stsill part of the question?

Anyway, sound like another p&c advetnure indie...
So, question: could you let us know what these voices are telling you?

I was talking about myself! :D
Not a point&clic, not adventure, not indie.

I made a mistake though: I here ONE voice in my head. Just one. A female one.

You must be awfully rich to spent an entire day in a restaurant ;)

Were you hearing that voice from the very beginning of the game or was it added to your mind after a few plot twists?
You are human, yet you are not. Does it mean that you are part human and part demon? Was your father a super star in the underworld?

Since English is not my native language as well, your sentences are quite comprehensible for me ;)
Only a voice or perhaps there were some images of that female voice person, sexually appealing demoness maybe?
