Gamified speech and language development platform for children aged 3 to 12, currently in production for iOS and Android. The product spans seven districts: six preventive and one clinical, with seven Masters, nine therapeutic protocols, and a content architecture already defined and partially built. We are looking for a game designer to join the project in two stages. The first stage is an independent critical review of the current design — not the execution of a predefined brief, but an honest assessment of where it stands and what should change. The review should address the soundness of the core mechanics across age bands, the coherence and pacing of progression across districts, the cohesion of the product as a single experience rather than a collection of modules, and the appropriateness of session length, reward structure and difficulty curve for young children on touch screens. We expect comparison against best-in-class references in children’s games and educational apps, and a clear point of view on what to keep, what to rework, and what to cut. The deliverable is a written assessment with concrete, prioritised recommendations and the reasoning behind them. The second stage, contingent on a successful review, is to lead the design through to production. This includes finalising mechanics, screen flows and progression; directing the illustration work in collaboration with the illustrator we are selecting; specifying animation and audio behaviour with the development team; and shepherding the design across all seven districts until release. This is a long-term engagement and the primary creative role on the product. Compensation and scope for each stage will be agreed upfront. To apply, send a short note, your portfolio, and one example of a previous design critique or audit you have led.

It’s tough when you have a clear desire for an exhilarating action mobile game, but all the key choices around story, camera, and mechanics are still wide open. The uncertainty can stall momentum and make it hard to see how your vision can become a production-ready concept that’s both fun and commercially viable. You can expect a fully detailed Game Design Document that nails down mechanics, camera style, progression, and fair monetisation, along with mood boards and a short prototype that shows your core loop feeling great on mobile. First, I’ll listen closely to your rough vision and ask targeted questions to capture your ideal vibe. Next, I’ll shape the GDD, visual materials, and prototype so you can review and tweak each part. Finally, I’ll refine everything into a cohesive package ready for your approval. What’s the one feeling or moment you most want players to experience in your game?

I can help turn your rough vision into a focused, production-ready concept by first mapping out the core gameplay pillars and camera approach that best fit a fast-paced action loop on mobile. Based on similar work I’ve done for action titles, testing first-person vs. top-down perspectives quickly in Unity helps clarify which feels most engaging on touch controls. I’ll deliver a clear Game Design Document covering mechanics, progression, and monetisation that supports fair, session-friendly gameplay. Alongside that, I’ll create UI wireframes and mood boards to nail down style and flow. For the prototype, a grey-box Unity build will let you feel the core mechanic and camera choice in action early on. Are you leaning toward more skill-based or casual play? Also, do you envision energy or currency systems for monetisation, or something less intrusive like cosmetic sales? Knowing this will help tailor the economy to your audience. I’m ready to start shaping the foundations so the game’s fun and clear from day one.
