Hello!
PROBLEM
If you're downloading the file last-word-win.zip you might encounter a bug upon loading.
SOLUTION
Instead download Last Word (D22-M03-Y2020). The only difference between them should be the save file location. This file should work, but let me know if it doesn't.
WHY IS THIS HAPPENING?
The simple answer is that the engine being used is a bit old.
The long answer is that the game, by default, saves files in the same folder that the game executes from. This means that if I use Butler to update Last Word onto ITCH, the save files will be overwritten upon update, possibly erasing the save data from older players. To fix this, I rewrote a script that attempts to create a new save location external from the Last Word files. However, this doesn't always work with every computer, and until I can find a full functional workaround, there are multiple files that can be downloaded. Sorry about that.
Please let me know if there are any more issues with this even after using the alternate downloads.
