I understand the steam page doesn't mention it's from him (he keeps his indie efforts separate from his vanillaware work) but it is, it's an enhanced version of a game he released last year that was made by him and Hitoshi Sakimoto.
It is wild that we live in an age where the founder of Vanillaware, the director and writer of most of their games, alongside one of the most beloved composers in the medium can release stuff on Steam without anyone noticing.
