Last time i checked SHE(yep, the dev is a lady...or at least she says so) was able to get like 800$/month...which is the above the medium wage (for a part-timer)(or the minimum wage for a full-time job) in Italy(how do i know? I live there), which btw is a lot if you consider that every 4 months it's 3200$ and she releases like 1 release a year...and then bragging about being busy...
I don't like to throw shit on people...but i'm not insane enough to even think to be a patron of a person like this...unless she tells me where the money goes...because as far as she told us she is studying...who can tell if she using the money for paying some tuition or other unrelated stuff to the game?
