Very intriguing story so far; I'm really enjoying it! The way you've characterized the 3 "guardians" is very well done, especially with Marrow and his very subtle hints of a deeper... something going on with him.
I do hope that we get to meet some more side characters though, to flesh out the environment, but after we get to spend more social time with the guardians ;)
My only criticism is I don't like the way the dialogue pauses (I think at commas and periods?). I read pretty quickly, so I hate rolling text, and tend to click 2 times to force the entire scene dialogue to show at once. So It's kind of annoying to have to click 2 or 3 times, or more, to get through all the pauses of each dialogue scene.
Also, while I for sure know that life happens, pleeeeease don't let this become an abandoned or "twice a year update" VN, it is exceptional compared to a lot of the gay/furry VNs out there. I can tell because I actually am more excited for the story continuation than the inclusion of the NSFW CGs (though I am looking forward to "getting to know" Rhoune a little more physically haha).
