The author has submitted some fantastic stuff for prior game jams, and this one is no exception. I would be willing to call the gorgeous UI one of the best I've seen in any furry visual novel, and the different styles add a lot to the storytelling. The sprites are equally good – though it is sort of unfortunate that we spend comparatively more time watching the stylized monocolor art in the jam version, since it is very pretty but just not as quite as visually interesting. I think the only actual criticism I have is that flashlight effect affecting the entire screen, non-diegetic elements included, maybe doesn't feel quite right; having to use it to read the narration made for a fascinating, unique experience, but the spacebar-hostility was a little annoying, and I have mixed feelings about whether making the counters less visible worked or not.
I would call the story enjoyably, deliciously cheesy and confident in its genre; you get the essential themes and beats of military sci-fi, and it's just all so moody, especially when complemented by the atmosphere of the visuals. The character voices are good, too. Though I yet again find myself unable to make definite statements on unfinished work, I will say this: I'm not sure how well the bifurcated structure pays off on the whole. It feels like many scenes end in a way that fails to keep the narrative momentum going; for example, I think the first bit in the facility could afford to incorporate a stronger plot hook. That being said, the material itself is written well enough that Geiger remains a thrilling read throughout, and it is of course possible that the true purpose of the structure awaits in the upcoming parts.
All in all, excellent work, with a couple of question marks that I'll wait until the full release to make up my mind about.
