My bad it was $7 and it was on August 3. There's an issue with itch possibly. I thought it better to reach out to you in regard to it. Ok this is weird, Itch is all over the place. when I click on the top banner that says I already own the game, I'm able to download the version in question, but if I access via any other method or angle, despite being logged into itch in all those aspects, itch gets a case of the stupids and acts like I don't own the game. I can make a video of it so you can see the inanity.
So it's not you, unless there's some extra thing an itch content creator has to do to make the thing act right across all ways a game be viewed for download on itch. I'm willing to blame itch for it tho.
