Meowingtons Simulator is not the type of game I would expect. Coming from Oberha5li Studios - the games studio co-founded by Joel Zimmerman, the man behind the mask of deadmau5, this is a ragdoll physics based music game. Essentially as the tracks roll you control deadmau5's cat, meowingtons, to create dance routines and move to the music.
There is an absolutely ridiculous announcement video that does very little to really introduce the game but does seem to hit the right note to highlight the absurdity of the whole affair. But hey, I love deadmau5's music so I'm definitely in for learning more. But what the game essentially seems to drive at is you can customize your DJ and customize your cat, unlocking new cosmetics as you play. You can join up to seven other friends in a rave, and the core play loop is to "control Meowingtons’ head or butt independently using simple impulse sliders. Launch his limbs, pose mid-air, or smash into the club walls—all while grooving to the track. The result? A glorious mess of rhythm, ragdoll physics, and feline flair."
You can pick up Meowingtons Simulator on Steam. While I couldn't find any readily available videos of the gameplay, I did find this one of meowington dancing in real life. Press F for meowingtons.
