Hey, did you maybe forget to add that it's a windows/mac build on the uploads? The itch app doesn't seem to recognize the new version, but I had no problems with the last one.
I can download them through the download page, but since it isn't marked for windows, I can't just click update.
You need to add the operative system on the upload (old picture but should look similar).
When done correctly, you should be able to see the windows/mac icon next to the files here on the game page.
