Before even clicking on the game. Love the art style and color palette you chose. Especially the text boxes (I know it seems like a small thing but my text boxes always seem to be a default rectangle with rounded corners.
After playing the game: Still love the art style and the music (especially the bells and vocalizations) really sets the vibe for the game which is perfect. Operating a machine for the patients is something that I have not done in a video game before and I thought it was very creative. The micro games were fun but became somewhat repetitive after a couple of patients. One feature I would love to be added is for the power button to reset the micro game. There was one time where I was trying to reverse the direction of the waves and clicked left so many times that the frequency of the wave literally became a blob. Small feature, but I think it would be a bit of a QOL improvement.
Overall, I really enjoyed playing through your game. With a bit more variety in the micro game department, I could see this game being even more fun to play!
