The gameplay is centered around biking, exploring, recording photographs or audio, and encountering local people. The player character is there in the critical moment, just as everything is about to change. You are not there to stop the change but to bear witness to it, to make recordings and attempt to understand what is being lost before it’s gone.

Really interesting premise, beautiful art style (with Japanese and obvious Ghibli influences).
