Cool concept! The graphics are nice and the game design is definitely cool... Here's what I'd change though, although some of it might not have been possible to implement in a game jam. 1. A mute button / volume slider. 2. Scaling Unity Canvas - Canvas mode: "Scale By Screen Size". 3. Make it more obvious when I'm in solo motion or rewind - half the time I clicked it and I didn't notice. Finally 4. Have a webgl exported version on the itch page, it helps for people to easily play and rate your game because they don't have to download and unzip it, I think this could certainly help bring more attention to an overall well made and well polished game!
