I think that might be because every file requires a minimum donation. If you click on "No, thanks just take me to the downloads", no files will show up because none of them are available for free. If you want to play a free demo, you can find it on my Patreon (version 0.5b). The link to my Patreon page is at the top of the description. I'll also try to upload the file demo files here so this doesn't happen again
