It is a new page, so it is a warning which should be gone by tomorrow (19.14 UTC) the latest. If you care to try again after that, it would be great to hear what you think.
In any case thank you for coming back to us and for the rating as well!
Edit: the warning is still on, I think itch.io takes a little longer to take it off. I am not aware though of players having issues with the download so far or they would have said so. Just for you to know :)
