I’m creating “Brain Lock,” a mobile escape-room puzzle designed for teenagers on Android. Gameplay revolves around realistic, story-driven rooms where each scene hides logic-based riddles, combination locks, and interactive objects that must be pieced together to progress. To keep retention high and monetisation gentle, I want hint-based rewarded ads integrated so players can choose to watch a short video in exchange for clues. Visual direction is grounded and lifelike—textures, lighting, and props should feel tangible on mid-range devices without sacrificing performance. Whether you prefer Unity, Unreal, or another Android-friendly engine, your workflow just needs to deliver crisp realism, smooth touch controls, and quick scene transitions. Key deliverables • Playable APK and source project with at least one fully polished room that showcases the core loop (explore → solve → unlock → advance). • Modular architecture that lets me drop in new rooms and puzzles without deep re-coding. • Rewarded-ad integration (AdMob or similar) tied cleanly to the hint system. • Basic analytics hooks so I can track level completion and ad engagement. • Clear documentation covering scene setup, puzzle scripting, and asset pipelines. Build, test, and hand over everything so I can keep expanding the rooms after launch. If realistic art, smart puzzle logic, and smooth Android optimisation are in your wheelhouse, let’s lock in the first room and set players on their escape.
