As you can see on the page, downloads are available for 6$. Price is the same since the game is first published and clearly displayed. Almost 100 people bought & downloaded the game without a single problem.
So i believe it's rude to accuse someone being a scammer and claiming there's something to fix. I would've gladly shared download links with you to help you even the amount you "DONATED" is less than the price if you were a kind person.
So maybe you should read the page before someone thinks you are falsely accusing people.
