Norikire! Hina-chan Stamp

Hina-chan's mobile device has failed in the specific ways that matter most: the text input and microphone functions are both gone. She still has to participate in ongoing group chats with Nitori, Suika, Joon, and others. The only tool she has left is the stamp function. The game is about managing those conversations using only stamps, responding to whatever comes up without letting anyone notice that something is wrong.
