I completely understand having to rush and not being able to add things you want! Me and my friend's game suffered from that greatly since we didn't start until the third week in. And honestly, I'm not sure how you could have ended it better, either. Maybe with a short sequence of the character waking up, and a little more story dialogue? And yes, this is definitely horror! I view horror as more of a "theme" than how scary it is, since whether someone is scared or not is completely objective. I, for example, am not phased by psychological horror at all, but it's all still horror. So yeah, the themes in this game, atmosphere, and events that happen 100% make it horror. I hope that makes sense! ^^
