hi! I'm the lead dev. Could it be you're using the itch io app? I never tested it on the itch io app. When you directly download the zip folder from the itch io webpage, it should work. We haven't had any problems for the 1+ year it's been on here, so I'm wondering why it's showing empty for you. A friend also just told me it can happen that Window Defender might delete some downloaded files automatically, so I would check that too, just in case
