I don't know what I see when I try to download it with the app here, but would this work? It's an explanation from another dev that might help.
What I'm saying is, I would like it to become downloadable trough the Itch.io App.
The downloadable is v0.3, but after reading it I revised the file and the app check wasn't on, sorry about that, is an easy to ignore checkbox
That was an answer from another dev, so that is the only thing that I can offer to make it aviable for the app, a checkbox?
