A plugin that changes a block above your head to bedrock. It's made for fun, not to play a normal survival game, but when you want, it's kindda challenge :).
Commands: /startblockchange - starts changing blocks; /stopblockchange - stops changing blocks; /blockchanger info - shows a list of commands; /blockchanger reload - reloads config.yml.
Config: In config.yml you can edit prefix.
