The little hero starts to laugh when shooting a lot. It is bound to the number of rounds per second to make him start laughing, every weapon has his threshold. Or when he shoots two or more targets in a row.
It makes the game more fun.
I'm thinking of more little animations like the love it animation for picking up ammo. Currently, I'm thinking of a cursing animation, unfortunately, I can not use the hits I get because we die too easy and I don't want to change that. He curses when he stucks somewhere maybe. Or when he struggles with something.
