Sorry about that!
Could you contact us by emai (shadowportalgames@yahoo.com)l and include your itch.io username or your purchase receipt? We'll take a look and help figure out what's happening.
One possibility is that you've run into our release schedule. Older builds are available through the $3 access level, while a newly released version gradually rolls out through our $10 → $5 → $3 release system before becoming publicly available. Right now, the latest build is still in the $10 access phase, so that may be why you aren't seeing it yet.
If that's not the issue, we'll be happy to investigate and get it sorted. 💜
