It is great that this plugin works, however there is no way to config it. Could I suggest making a editable config, also adding it so you can toggle if Y-1 is breakable? I don't want my players able to get into the void, I just want them to be able to get down to the bottom layer of bedrock.
Very good plugin, players seem to enjoy this,
however the config is inside the jar and not extracted when loaded so changing the command from /bb (used by another plugin) to something else was a little difficult.
Overall a great plugin though, defiantly worth 5 star
