Hey Cryswar,
there seems to be some kind of problem with the itch app.
I purchased your game a while ago here on itch, and even though you just released version 0.26, itch only shows me version 0.25, the Demo version, as available. If I go on the itch website in my browser, it tells me I purchased your game and gives me a "Download" button where I can download the latest build. The app doesn't give me that option, and I also was not able to let itch update to 0.26. I had to download it manually.
