I liked how each parts of the mechanics are introduced piece to the player at a time as the levels go on instead of shoving all the instructions into the player's face.
The game also seems to follow the theme of "rewind" quite well. Having the "run it back" being required in order to reach some parts of the levels really made it feel like the most important and notable feature of this game. However, I would prefer if I could have the ability to rewind after I'm done using the "run it back" feature instead of having to wait for the bar to deplete all the way.
The platform maneuvering feels a bit too precise in most areas. It feels like I have to land just right along the edges of each platform or I'll miss the jump completely. I would prefer if some of the platforms were moved closer instead of relying on hitting the edge each time. Having precise jumps in platforming games isn't a bad thing however, it just needs to be incorporated in a way that feels smooth. With some platformer games, they incorporate a feature that gives a grounded check a slight delay before determining that the player is off the ground.
I also would have preferred if the "rewind" player body could pass through the past player body with the exception of jumping on its head. There were a few times where upon using the "run it back" feature the rewind player ended up colliding rapidly with the past player and ended up falling off the stage.
This might be a personal opinion, but I'm not sure if I'm a fan of the music that plays. It sounds more like something you would hear from a bubbly commercial rather than a video game. The music also seems to repeat the same melody multiple times rather than changing into a unique tone, so it got pretty tedious listening to the same set of notes throughout my playthrough.
