Oh, man, I could write a dissertation on the troubles and lengths I've gone to to get good artwork on a budget. As for music, well, the struggle carries on...
Sure, write your problems and resolutions down. It's almost certain that other devs will feel the same way and be grateful.
I think that appealling to streamers is different, though. Streaming is even more of a crowded field than gamedeving- to be a streamer, you need no more technical expertise than to have a camera on your PC and the ability to download OBS. I'm not mocking them- it's easy to start up but you need real talent to make it worthwhile for people to tune into you day after day.
I'm just saying the integration between indie gamedevs, and people who will stream indie games is pretty shit, and I'd love sites like itch io to make it easier for everyone.
