Thanks for the feedback. Just like everyone else, you've also complained about the issue of the enemies "Health'. I have written down all the ideas I've gotten from every comment and implemented most of them. After the game jam is over I will make the final update and give for a play test.
And for the barrel issue, I don't know why but I thought I set the barrel collider to "Ground" layer 😅, so that the player can gracefully stand and even walk on it, but I guess in future updates I will just remove the collision from the barrel and the "Characters".
Thanks for trying out "Modern Fighters", now go play some other game :P.
