Normally there's a 'claim' button not a 'download' button.
Yes it can be downloaded but it can't be "claimed" .
If it can't be "claimed" then it doesn't stay in ones Itch account ,it's just a fly-by-night one-time download :)
I searched through the settings and help but i still don't have a solution.. Maybe claim only works if someone actually paid for the game? Until that miracle happens i won't know for sure, y'all have to be contempt with just keeping it in your collection i'm afraid (it will stay pay-what-you-want forever anyway)
This one was posted on reddit ,y'see ,it has a "download or claim" button.

as opposed to just a ' download' button.
To be honest i'm not 100% sure what the different download methods mean ,someone just told me that it has to have a "claim" button if you want to have it permanently stored in your Itch library.
Anyway first world problems methinks :)
Thanks for the game !!
