Oh those guys? Yeah those are just the dozens of professional voice actors we could afford to hire with our tiny baby game studio budget! And those guys? Yeah that's just our 7-person "engineering" team. What do you mean your entire studio is 4 people?

But they do this level of polish with voice actors and music since Bastion, their first game. Logan Cunningham and Darren Korb are part of Supergiant.
Bastion was a much more limited game and reflects their status as actually indie at the time.
Indie doesn't mean low quality, it's about resources that's all.
