Things I liked, Overall you made a very good retro arcade game! Really loved the artsyle with it and the controls felt super smooth. The sound track was also a bop and helped to make it even more hype.
Things I didn't like. The rewind, while sometimes useful, I felt required too much forethought to be useful in a pinch. The fact that you couldn't use it after you died made it feel like a slight waste as it is already difficult enough to get fully charged up. I feel giving that to the player would allow to feel that at the very least they didn't waste there rewind by not using it.
Overall though a very fun game and I think you should be very happy with where it is at!
