I'm following the Sokpop collective, they are 4 developers that have committed to releasing 2 games per month. The main source of income seems to be Patreon subscriptions, but games also get released on Steam.

Every one game is quirky, vibrant and fun. For few of them I was disappointed that devs moved on instead of continuing working to bring out the potential, but after a while they would return to same concept and release a sequel.
