GRAZZZZZZZER NEED HELP

@grazer My Game Footnight has some bugs that I can’t figure out how to fix.
First When someone gets a gun it gives the other person a gun.
Sometimes one person can see you but the other can’t.
Use 2 computers and press Online at the exact same time. Then use the arrows to move your guy into one of the black tiny blocks then it will teleport you to the regular world. Then use the arrows to run into a gun or chest then x shoots pistol z shoots Machine Gun C shoots Sniper.
Thanks.
If anyone wants to try it here it is:
