I don't really like all the monetisation stuff, I started with donations but it does not work really well. So I prefer to put cheap prices on my games and host many sales, usually one per month (when I remember). It's probably not what I should be doing but I hate marketing and finance. Hence why I don't hesitate to publish small prototypes for free, to share stuff.
I just want to make games.
Like I should be promoting my games everywhere and all the time to make money to auto-finance all of that. But I just hate that.
Edit: also sometimes you just work like a demon on a game, and after a few months you realise nobody will ever care about it, or it was just crap all along. It's either I move on or I'm devastated.
