Why Android is not free?
Any guesses??
Unity asks for money for downloading?
It helps deter minors. Android devices are the most accessible device these days. It covers the devs' backs. The only people that would have an issue with a $5 payment are minors after all.
Not at all. It's a reason. If you have problems forking over $5 then you're a minor. It really is as simple as that.
Other currencies exist 😔
If those currencies are having difficulty paying $5 USD then they have much better things to worry about than a random porn game on the internet.
