Hi everyone i do like ask a item and a ffc script for the item.
Super Power Bracelet: The item could be simply a update from the Power Bracelet that allow you to puch heavy blocks (4x4 combo block) that only work if the player get the item. or else the block will not move an all.
Big Block (4x4 combo blocks) ffc: The ffc script could react as a solid combo and as normal block but the item script will be required if the player wants to push thoses block. The block size could change depended the setup of the H and W sizes of the ffc script.
