I think the game would need heavy exploration focus with a context driven story and/or disembodied voices similar to Ori and the blind forest. Some gameplay additions wouldn't hurt, since that's what's lacking the most atm imo. Not necessarily combat, but more efficient ways to mive around, mobility locked areas, collectibles and hidden lore. I don't have time to be part of this, but those were my two cents on the topic 🙂
