It’s pretty much following the Steven Universe mold. In fact, I’d argue it’s a bigger influence than I Have No Mouth, and I Must Scream. It even has the same “character gets corrupted into a monster” bit. Though I’m sure SU itself borrowed that from Madoka.
Both shows set up a fun premise that they mostly ignore so they can focus on therapy sessions for the main cast. SU promised action adventures, Digital Circus promised horror, and both end up teasing a big twist that many people probably guessed already. If they go for the “happy ending” that’s really about coping rather than giving the characters what they want—because that’s supposed to be deep—I’ll be 100% convinced it’s Steven Universe inspired.
That said, to Gooseworx’s credit, Glitch doesn’t waste your time with episodes about characters you don’t care about. The writing is tight. And unlike SU, kids actually like this show. While SU is stuck with man-children despite being the actual kid’s show.
