I currently have a free published game on itch and I had probably 10% of players tell me they thought they had to pay leading them not to download it at all. I'd suggest adding a $0.00 button? Or a free button where the $1.00 button is?

Alternatively, write in your description: Payment is optional. To get the game for free: Click "Download Now" then click "No thanks, just take me to the download".

Seems they do not bother to read, before clicking.

It literally says Name your own price, next to the button does it not?

And then

This game is free but the developer accepts your support by letting you pay what you think is fair for the game.

No thanks, just take me to the downloads

I read a lot of comments on games, and I do not remember encountered people complaining there, that they thought a pay what you want game was paid. 10% sounds substantial, so I would expect to see this issue popping up here and there.

You can also just type in zero... lol

People just click NEXT without hesitation, ironically they are concerned about a small donation but how do they avoid getting scammed?
