As for DIY game devs, I really enjoyed Tom Happ’s Axiom Verge series. The artwork and level design, especially. I’ve seen a couple interviews where he kind of brushes off the praise for the musical aspect - and I agree. I think it’s the weakest part of his games. The music fits incredibly well, but it feels a lot like someone noodling on a keyboard until they reach the appropriate level of spookiness.

But ultimately, all the components work well together, and the games feel like one person’s mad vision.
