I am disappointed, but I hope you try again.
I was very eager to play this game after I saw the trailer. I am a huge horror fan, so I am always looking for more horror games. This game was very interesting to me. I thought it had tremendous potential. Sadly, I do not think it reached it's potential.
My problem is with the mood and atmosphere. I did not feel that the mood was set properly, or that the atmosphere was immersive enough.
The game was too short. It felt very rushed. I was never able to immerse myself in the atmosphere. There was not enough time to build suspense.
Show, don't tell. I wish you had shown the introduction rather than write it and leave it for us to read. A video showing the ghost and the girl's reaction would have had much more impact. It would have helped me associate with the character and care for her. The text introduction is jarring; a video introduction would have immersed me in the game more. As it is now, the introduction is so quick and uninspired that I could not emotionally invest in the character. A video conclusion would have been much more satisfying as well.
I wish you had used voice-acting rather than text boxes. Text boxes distract from the experience and the atmosphere, which are critical to horror games. The dialogue sections would have tremendously from good voice-acting.
The musical transitions were jarring and distracting. I noticed several times that moving from one screen to another the music would change dramatically. Sometimes the music would suddenly disappear; other times it would rise unexpectedly. These poor transitions definitely detracted from my experience.
Despite all of my criticism, I would still like to see you try this sort of game again. The graphics are this game are beautiful; they really established the mood. The story was cliché, but that was OK; it was a simple and effective story. I for one did not have much trouble with bugs. I am terrible at puzzle-solving in point-and-click games, so I will not comment on the difficulty. I hope you make another horror point-and-click game for Halloween. Just remember to work on the length, introduction and music.
