This was a fascinating playthrough. I overall very much enjoyed this concept of "living" and "dead" spaces. For the game jam's sake, I'll give my thoughts in a noted format.
-The visuals were my favorite aspect of the game easily, I have a huge soft spot for highly textured visuals and this is exactly what I look for in new games. The use of color was entertaining, and I feel introduction of the house's spaces were carefully done as well so very great job with this :)
-The lack of sounds both contributes to the unsettling nature of the game, and also takes away from its immersion, so I'm not entirely sure how I would rate this based on audio, but your story telling would probably be greatly supported by sound. On average, I think audio will be expected for most VN styled games so definitely consider a partner or potentially learning some audio stuff if you're interested.
-Your writing style is concise, but also I enjoyed when you let it get unhinged and started repeating phrases, or letting some anxiety induced thoughts cut through. Very solid writing overall.
-The endings were unique and interesting, although I kind of found myself hoping for like one more ending, maybe one that connects all the house concepts together - mainly the fresh blue, the old rotting orange, and the virus itself.
Your stuff is right up my alley though, so I'm keeping an eye out for your future games :)
