I’ve released my game Flipon https://flipon.net end of 2020 and while it’s not a huge success, it’s still quite a consistent flow of income (300-500€).

Doesn’t require much maintenance, maybe some new content soon.

I'd say that sounds like a huge success, 300-500 euro is a decent extra bid of money for most people.
