Thanks for the feedback, it's my first game so most things I did where very off cuz I don't have much experience with it, I do know about unity default rigidbody physics being bad but I didn't have the experience or time to make it better, about the health and shooting it's actually the other way around, I had some delay before the enemies were shooting but noticed that the player can shoot them before they get the chance to fire which felt boring, so I added no delay, I wanted to add health to enemies instead of making them one shotable and we adding the delay but didn't have the time to do so, anyways thank you so much for the feedback, I really appreciate it :D
