Thank you so much for leaving a great comment and playing my game!
I'm planning on improving upon the game after the jam is over and will be improving the things that you pointed out.
I actually had a better idea to implement the theme but wasn't able to make it, because I definitly overscoped. My idea was to give each mage the ability to rewind themself to their position from 3 seconds ago. And if the mages worked together they could instead of that rewind the entire world 3 seconds. I didn't have enough time for it tho so at the end I was kinda improvising with how I've had implemented the theme.
