Hiya, this was certainly one of the more interesting visual novels I've had the pleasure to play in the past bit. The art is very well done and the music superb, the atmosphere is set nicely with the creepy house, nighttime setting and creepy sounds.
It's definitely a short game, but that isn't necessarily a shortcoming, the game seems to use it's limited time to introduce the characters, what they are, and the setting with enough detail. However, I was left wanting to know more about where these characters came from and just who or what the Paramedium Guild is.
There are a few grammatical mistakes sprinkled here and there but nothing that severely detracted me from enjoying the game. As mentioned by Raithias, I had Nina call me by the incorrect character name, it's included in the video but I just overlooked it, no big issue there.
All in all, it was good game, I hope you don't mind but I recorded a short let's play of my time with the game.
Cheers and best wishes to you.
