to answer your question, no it wont, but if you are still unsure, you can go into the game file, find the file name "www" under that, there is "save".
move it to desktop, download the new version again, and put the "save" file with the one in your desktop.
It didnt worked I always get an error I think its bc they are different versions. I now downloaded the itch launcher but I would need to start there from 0 again TT is there no way to import my progress from the older version to the new version?
