Adore your thumbnail!! Here's some feedback I had during my playthrough!
Immediately I was impressed at how much world building you got done by (the examination of) set dressing!!
The music eventually ended after taking final patient of day 1. Also, music eventually ended while idle on day 2; started back up when next client came in. Just some overall music looping issues.
As days progress, the decline in music tone immediately changed the mood! Very clever, and smart reuse/extension of asset for the theme of this game. The increasingly discordant, layering of the keys when Hisako gets more tired is great touch.
The contrast between the severe heavy moment of choice and the pink adorable graphics is so thick that it's palpable. Love that you all were able to create it in such a short amount of time. Good Job!
I'm an overall huge fan of the art, and art style!
