A really great game! I enjoyed the art, the setting, the story, and the general concept.
One thing I'd probably add is the ability to skip the first two days after completing one or two endings, or have a save option so we could save the progress of those days. Maybe it was my impatience, but knowing what was happening I wanted to get to the more important decisions sooner and felt a bit frustrated over having to repeat that so many times again.
But I reaaally enjoyed how everything progressed gradually either way, felt creepy and engaging getting the reveals of the other "illnesses" and what the doctor was actually doing.
Overall, I really enjoyed it. One of my favorites so far!
