Spelling and Grammar: 10/10. No spelling or grammar mistakes as far as I could see. Idea Originality: 9.5/10. I don't think I've ever seen this idea before, though I can see some influences from Lovecraftian horror. Idea Execution: 9/10. Could it be improved? Probably. Could I do better? Absolutely not. This story is very well thought out and seems to have a lot of effort put into it. Dialogue: N/A. I don't feel like a couple of lines from the shadows is enough to try to rate XD Character Development: N/A, but that's okay in a short story like this one. Overall: 9.5/10. Like I said before, there are probably points for improvement that I didn't find, but it's already excellent as is. Well done!
Many thanks to @Theoddity for letting me review her story. The notes she put in got deleted when I remixed, so if you want to read those I recommend you check the original project.
