extract the attached file, and put it into /game folder (NOT the game's main folder where the .exe is located)
Then start your game as usual.
Maybe you get a message that the mod is installed - and maybe that you may apply a mod-update.
Just ignore all these stuff for now.
After done all that, hit ALT + M. You get a warning popup which you can chose whatever you like - doesn't matter at all.
You should now see this screen:

Klick on "search" on top left and search for "walk" (part of walkthrough).
You then should see the 3 attributes below - klick on walkthrough_mod_enabled "False" to toggle it to "True.
DONE - you can now close that window - enjoy.
Note:
This Mod is universal and works with all RenPy games. You can search for every values, names and even simply rename HARDSCRIPTED character names by search and replace or renaming.
In other games, you maybe know that you have 134 Money, but you don't know the variable name, just search for 134 in VALUES (toggle "variable names") , then hit SEARCH... and voila: variable found if you did right - go change the value to 100000 and you are rich - no grind anymore.
This mod doesn't change any original files at all and you can easy remove it again if you want to.
It's kind a must-have for all RenPy gamers
