itch.io

i paid $5 and downloaded "Donation Only Build - Windows version b16.1" however when i unzip that download and run the game it it showing me Public Rough Build 15.  This appears to be the same version as the "free preview".  Is there a difference I am missing?

I completed the story with Eva, on versions 0.5.6 and 0.5.7 since then we i visit college i don't get the credit for it on the weekly checklist, so am never able to complete the checklist.  am i missing something?
