I really liked this one. I'm not normally into VNs, but this one was interesting enough both in story and in characterization that I want to see where it's going. Even though I tend to avoid anime VNs, I really enjoyed the art-style and I especially like the relationship between the two roommates. I do wish there was a little more gameplay, but I also understand that this is a novel AND a demo, and that there will be more in the future.
Overall, good job. The writing was really well-done, and I honestly can't wait to see the full game. I just hope there's more horror to it. :) This feels more like it's leading up to something horrific, but it cut us off right when things were really heating up. Keep it up!
