I'm going to be blunt here. First off, I'm not much of a horror game guy either, so I'm not well equipped to judge how good of a horror game it is. That said, the visuals are clean, and the I think you did well in using the lighting to provide both challenge and suspense to the game. I was disappointed, however, because most of the objects were too small for me to really appreciate any detail, making the whole scene look bland in my opinion. The lack of any audio really hurt the experience, too, since most horror games (to my knowledge) rely on both the use and skillful absence of sound to amplify feelings of fear and anticipation, but the complete lack of audio along with the simple ball of light graphic you used for the ghost was entirely unable to evoke any sense of fear. Many horror games are able to compensate for simplistic gameplay (like that of your game) with the aforementioned fear, but without that fear, it felt like I was just cleaning up fallen objects. All in all, I think that the game would perform much better if you could at least incorporated some kind of ambient noise and sound effects in the future (i.e. flickering light sounds, some violin shrieks, those sorts of things). If you're able to do that and some more polishing, I'd say the game could get somewhere you'd be satisfied with.
