Spoilers ahead. Play first, than read... or don't. I'm not your father.
Theme: I wasn't seeing it, unless it was like, the hour being a 25th hour in the day?
Story: I think you started with the wrong part. I think you would have been better served with leading up to the hour if it was at the party instead of the flashback, or instead lead with the hour. The morning after was a lot of pining for the poorly remembered wolf and going "what happened?"
The hour was reminiscent of some manga I've seen before, and in those first chapters, you want to dive into the action asap given that's what the narrative circles around.
Presentation: Green wolf cute! Needed more on screen. Little bappy friend. I appreciated the blue filter for the hour.
Too many of the backgrounds weren't full screen, and no music mostly throughout. I would have appreciated some more music, even if creative commons. We expect audio, even if it's just kinda there, as this is a multi-media experience with expectations built upon it.
If you did NVL mode, I wouldn't have been as upset with the only-background for most of the work.
Creativity: I wanted to be more invested in the hour, but we didn't get enough of it to understand what it was. If that was explored more, and what the monster meant and why...
Overall Thoughts: This might be partially due to this being within your Reverse series, but then my complaint is that this doesn't have the legs to stand on it own. The narrative is tied to your other work, I presume, and in that regard, this can't be read solo as it stands.
It may have been more conducive to either give more from your original work, or to carve out another item to expand further upon in the work, rather than this sort of confusion narrative that doesn't sufficiently get resolved.
