By doing the glitchwrap in the grass area, and then flatwalling into the castle, and proceeding to use the window glitch, you can theoretically get a time of around 45.90. Pretty damn pog. (I did a run like this using pauses, the actual time of the run was 1:09.44 but with pauses it was 45.92, nice)

I was thinking more of a sub-category of no tools.
