We were in a similar spot when developing our narrative puzzle game. Bringing in a game design studio really lifted the weight off our team. They came in with structured processes, wireframed our systems, and provided documentation that clarified the flow for both devs and writers. What impressed us was how they merged creative ideas with real implementation constraints. Instead of guessing, we had data-backed mechanics and better progression pacing. Just make sure to ask for samples and go through a proper scoping process — it sets clear expectations for both sides.
