Chrono Trigger meets Guitar Hero was not on my bingo card, but I’ll take it regardless

You’re dead at the start of rhythm-combat RPG Nocturne, just arrived in some sort of afterlife waiting room after the apparent extinction of humanity. You get your bearings, and you soon meet up with another, only slightly irritating, small child. His name is Kimothy, which sounds like something you’d only say as a joke to annoy friends named Kim, and then only once because it would be stupid to say it again. It’s fine! Leaves flutter, rays of sun cavort through trees, and the music is utterly gorgeous.
