I was keen to try this game as it has some similarities to my submission.
You did a really good job. The rewind effects look great and the gameplay is quite unique.
It was a bit difficult to keep an eye on all the green circles to make sure they don't touch the red arrows. Sometimes a bit of luck was involved for me.
I think it would have been better if 'rewind' occurs when space bar is held down and stopped when it is lifted. I think it make the controls feel a little better.
Overall, great work. I really enjoyed this.
