I don't know how to send files via Itch.io and I don't have Twitter, so i'll just send picture of a file, opened through notepad. I don't know how your game is working, but it seems like it has closed before it finished writing down all the data. It happens no matter which way i close it. I'm using Windows 10
If you need the file itself please tell me which way to send you, The Man, The Myth, The Legend of Letters.
P. S. I dunno why Johnson, i just sometimes add it to other person's nickname
The screenshot is fine and you are right, it appears the file gets truncated when it's written. I've created a ticket for this bug: https://github.com/LambdaHack/LambdaHack/issues/302. It also contains a possible workaround. Please let me know if the workaround works for you and any feedback about the actual game (assuming it works fine this time, let's hope).
BTW, did you use a windows installer or the zipped binary to install the game? Unlikely, but potentially one of them may be failing in this way and another may be fine.
Reading the rest of you post, man, you are poet! :)
