Itch doesn't block games based on IP, nor does it even have a region blocking system, so thinking that Itch shows the message to everyone except your IP doesn't make any sense.
What does Itch gain by hiding the message from your IP?
Please try to be objective and calm before continuing with the thread, so that it is not a problem for others to try to assist you.
Try DOWNLOADING (not just reaching the link, but actually DOWNLOADING) your game with a browser in incognito mode or without being logged into your account.
Itch is not Steam, it hosts more than a million games for free for the vast majority, which means that it does not have enough staff to resolve all the questions and reviews that people need at the times they would like, so which you must be patient and wait.
If for some reason, you need to rush your case to support, in this same forum, at the top (where it says "View this community's rules..."), there are some rules (the ones that "No Time To play" told you to review) that inform you of the steps to follow.
