Ever wanted a kirby-styled block remover/changer gimmick in your hack? Well now you can! If the player triggers the bomb block, it will spawn a custom sprite that wipes out all the adjacent blocks one by one (on each explosion). See the readme for more info.
Oh yeah the tool for the explosion sprite is romi's spritetool 1.40 or higher.
the animated image below was made by me using licecap.
UPDATE: Fixed a buoyancy glitch. Address $019138 affects the sprite's interaction, causing strange teleportation when it shouldn't be (like destroying 1 block above the explosion).
