Hi, we have fixed some things, try again and let us know.
All of the mentioned files on the download page are still broken. When you look as the Mac download link on the download page (which is the only working file), it says that the file was updated 1 day ago. The rest of the links say that they were updated 51 days ago. Even the rar file for the demo on this page is broken.
Strange, we have tried downloading the files straight from itch.io and it's working fine on our end.
We had to re-upload the Mac version because it was not unpacking correctly as a .rar file and we changed it to a zip file. The other files should be working.
What program are you using to unpack the .rar files? Winrar is what we use.
