idea for the bombs, player touchs ceiling, which fires relay down to a round brick that appears as if it's falling from relay dissapear events, then at the bottom, it has a small delay, then spawns a small explosion with gun bullets going on the X and Y axis, and the destructable blocks will be onprojectilehit>self>dissapear? and make each player have 1 health :D
maybe i'll make this... it looks like fun
