Hi I'm sorry but what did you use to make this game? I was just wondering

More people need to play it lol

I just finished the game, in the end my character left with Ray and became friends with her dark side. It seemed like a bad ending and so I was wondering, is their any other, happier ending?

Short and sweet! Thanks for making it free.
