A small tool to help visualize and debug what happens during rollback, signal by signal.
Open rollback-debugger.tscn.
Replace the Subject node with the rollback-enabled node you want to debug.
Optionally, edit rollback-debugger.gd and set the State and Input history
fields' values to the initial states after the first _render_data() call, to
avoid having to paste the same values on each run.
Editable fields are taken into consideration and applied before every signal.
