NuzzleBug is a fork of the scratch-gui adding debugging support.

Description

NuzzleBug is debugger for Scratch. It allows controlling the executions of Scratch programs with classical debugging functionality such as stepping and breakpoints, and it is an omniscient debugger that also allows reverse stepping. NuzzleBug is also an interrogative debugger that enables to ask questions about executions and provides answers explaining the behavior in question.
