Interesting small game!
Despite the cute art style, the premise of the story is quite horrifying when you think about it. Nurses overworking in medical facilities is a very real problem in many countries, and I'm glad that your game sheds light on it.
I also really liked writing. Quirky patients' biographies made me giggle more than one time, and l found some of the lines that the nurse said quite touching.
In the description on the game page, you mentioned dilemmas and moral choices, but I didn't actually encounter any through my entire playthrough. There was never a point when several patients appeared simultaneously, so I would have to choose who I wanted to save. Is this some bug on the game part, or was I just so good? :)
Overall, an impressive game, both from a game design and technical standpoints. Nice job!
