Itch.io is running a crazy bundle right now, with all proceeds going to NAACP Legal Defense and Educational Fund and Community Bail Fund. Minimum payment of 5 dollars gets you tons of games and tools and media.
We jumped in at the start, because Black Lives Matter, and offered DragonRuby Game Toolkit, so your five dollars gets you a 40 dollar game development engine, even before you get to hits like Celeste, A Night in the Woods, Nuclear Throne, etc. They are still adding more stuff; currently there are 1,427 products in the bundle, which would cost 7,875 dollars separately (indeed, my header image on this post is already out of date!). The bundle is racing towards 5 million dollars earned, and they are still adding new things.
You can grab the bundle here! Offer runs for six more days.
