itch.io

I'm in the same situation as you (missed the kicksterter, bought in late).   

I was able to find the .6 version in my Itch Library (  https://itch.io/my-collections  Click the 'download' under Beamsaber).  In my case it was the last entry on the page - on account of it being alphabetically inferior to the rest of the entries.

Spoiler: The phrase "Header art is space battle" no longer appears in this book.  

Hello,

Have you been able to resolve this situation by following charlesmoore99's suggestion, or do you require that your download key be resent to you?
