When you set the price of your game to no payments, there wont be a download button on top of your page but rather one for every single file at the bottom. With the price set to "optional donations" there is one on top.
I feel like it should be atleast optional to have a seperate download page (like the one after "No, just take me to the downloads") because with the install instructions AND the whole other text its quite a lot to scroll in some cases.
