Here's a description from Steam:
Enter the Rhythm Dimension. A homage to classic arcade rhythm games (Guitar Hero, DDR), with a modern aesthetic and soundtrack. Match colours and beats, spin, tap, flick and flow through the juiciest beats in the universe. Supports multiple control styles including MIDI DJ gear on Steam!
Edit: at the time of writing this, I didn't realize that this game had 3.5K reviews on Steam, but literally nobody I asked knew about the game, so I guess it kinda counts.
