I love the space/ sci- fi atmosphere in your game. Some might say your movement is a bit floaty but I think that fits with your game. A improvements I would like to see are:
-Indicate what the objective is for the player
-less random platform placement maybe?
-an indication when time is going to rewind would be nice
-Allow the player to jump of the sides of the platforms. The platforms may feel unfair but if you extend the collider just outside of the mesh there is a bigger gap in time where the player can press to jump. There is a gamedesign term for this but I forgot haha.
Had fun playing, thanks !
