Guilty
 

I remember a space themed point and click adventure game that I played as a kid but never finished it cause I didn't know English back then.

I remember that when you start the game you get to choose either a guy or girl that has a gun. I remember the start of the game when you choose the guy that he's sorta captured by the girl and imprisoned in a room spaceship. you get out of the room by tricking a service robot into changing the light inside or something similar.

That's all I could remember, hopes it helps.

The game you're looking for is most definitely "Guilty".

Yep , that's it. Thanks a lot.
