Hey, im new here.

I dont know how to correct name it in the title, so ive just put this scrap in it. Is there any chance to make te button for "helping your developer", some kind like on youtube or other content creators? i saw only payment for downloading the game files, but i want to make free to play browser games, and not to force the pay.

Is it possible here, or if that so, how can make it on my account?

Browser games are already free to pay. If there are no downloads, there will be a button under the iframe labeled "Support this game". Any money you receive that way will add to your total as usual, and you can simply request payouts.
