I don't really do anything beyond making the odd Twitter tweet. I was really only writing Playdate games as a hobby but now I've got one of them on the catalog I should probably put more time into promotion, etc.
I've got a 4th game almost finished, you should see it released on itch about a month from now.
You totally should Sean. There's virtually no downside to writing a Playdate game,.You get a choice of languages, you don't need to pay for any resources to write / test / release etc (though Panic's Nova IDE makes debugging etc a breeze), and the community's always ready to help. Best of all you get real feedback from the people who play your game and I love how heavily weighted the community is towards positive feedback. I'm sure there's people who didn't really like Medial, but I'm only hearing from the people that did (which doesn't mean I don't get piles of *constructive* criticism / new ideas). I've found the whole experience very positive.
