Pretty nice celeste-like! The controls felt nice and the crowns were nice side objectives to go for. I felt the rewind mechanic was a bit underutilized and difficult to know when to use. It doesn't seem that it lets you rewind for very long and the screens where it is necessary to use, there is no visual indication that the blocks on the screen will be affected by the rewind. You kinda just have to come to a screen that seems impossible to solve and assume you need to rewind. I also got a glitch where my character fell through the ground and I was unable to continue. I've attached a screenshot. Overall, great platformer, thanks for making it!
