Really good for your first game, but i don't understand how you can control the chaos. Also, i think you could definetly make this a lot more difficult. I also think you should make it so that bullets can't be shot or pushed, to prevent them from being pushed, just freeze the x and the y position under the rigidbody constraints.
I hope my feedback helped you, it would be cool if you could check out my submission too: https://itch.io/jam/brackeys-6/rate/1175578 Thanks! :)
