hey so I was wondering if it's possible to place a Donation button on the page that my game is located on? if not, is it possible to put one on my profile? 

Reason I ask is cuz I don't think the donation button for my game is working. it's probably because my friend already downloaded it without donating. he wants to download it again to trigger the donation option, but it doesn't pop up. Does anyone know of any solutions to this? I'm open to any and all solutions.
