Regarding your game, I can say that it has a very nice pixel art visual style, and everything works perfectly.
One thing that could be improved in the game is providing more visual cues for interactive elements on the screen. For example, I liked the background of the main menu, but it took me a few seconds to realize that the menu was on the left side of the screen, and it seemed like part of the game's background. Then, in the hospital scene, it took me a moment to figure out how to interact with the doctor using the mouse pointer: I clicked on the doctor who told me to interact with the one on the other side of the counter, but to interact with him, I had to click on the counter in front of him. Perhaps this can be handled differently to simplify interaction with him.
