Really liked the GUI design and layout. The overall look, especially in regards to the main menu, mock-up software, chat system, etc. was sleek, modern, impressive and professional. I also liked the art style and Yuki's design. The voice acting was clear and nicely done as well. The falling snow in the background was a really nice touch to help represent the "winter theme" even though the story takes place indoors. I think the writing for the narration was pretty good and descriptive as well. I was never confused about what was going on and the writing had a nice flow to it.

My main critique is the pacing and overall structure of the story. I feel the ending (at least the one I got) felt very rushed compared to the rest of the story and cut off abruptly (though understandable considering this is a jam game, I'm assuming the devs just ran out of time). There were also some minor criticisms I made about the size of the dialogue text being too small (at least on my screen). Maybe consider including an option to enlarge it to make it more readable? There was also one point (the 'asking Yuki questions' section) where the choice menu got cut off at the top of the screen which can easily be fixed by having the choices split into two columns when there's more than a single column can accommodate.

Considering there's multiple endings, I'd also recommend including an indication of which ending the player receives as I feel it was a little unclear. This will encourage multiple playthroughs, especially if the player is unsatisfied with the ending they received and would like to aim for achieving a different one.

Thanks so much to the devs for creating a fun game and taking the time to read my review. I enjoyed playing and am looking forward to seeing more in the future! ^_^
