This one stirs feelings.
I replayed the game and reworted this comment.
I know nurse-chan is supposed to be the eye-catcher here but her characterization is really well done and moving.
It breaks my heart that the protagonist has to die even when he almost regained memory ablity, though I know this is intentional and realistic in some way.
Really good job! The game style definitely reminds me of Milk inside a bag of milk.
