I like the concept of your idea but I think you can make more out of it. It´s cool to have so much control over the time but I only used the pause and the slower ability since for me they were the most powerful.
I hope you expand your game after the rating period. Good luck!
I´ve submitted a local multiplayer game: https://itch.io/jam/brackeys-4/rate/722755. I would be happy to get your feedback on it. :-D (I also posted a comment on your topic)
