Hey, here is my honest opinion,
- I liked the soothing music, it fits the game you went for.
- I liked the graphics, nice pixelart
- Mechanic-wise, I'm not that impressed. You walk to a puzzle piece and the first two levels are completed automatically. When I was on the third level, I kept dying to the first spike when 'rewinding'. It seemed that I could not jump during the rewind because the player was somwhat glued to the ground. I retried almost 10 but I could not pass it.
- Story-wise, good idea, could use some improvement. It seems that the depressed girl is in a coma and remembers that she had to suffer troughout her life. Maybe it could improve with a form of text implemented into the game. So you get to know the main character (depressed girl) a bit more.
- Puzzle piece transitions were really neat.
Overall good submission. Was most a fan of the art, but maybe I'm just bad at platformers.
