Unity Developer Needed – Build a Mobile Hidden Object Game (iOS & Android)

I’m looking for an experienced Unity developer (individual or small team) to build a polished hidden object game for iOS and Android. The game concept, gameplay, and monetization have already been planned. I’m looking for someone who can take ownership of the project from development through publishing. Overview Players are presented with a highly detailed scene (Victorian library, candy shop, kitchen, pirate cabin, antique store, toy store, etc.). Each scene contains 25 objects available to hide. The player chooses 5 objects and places them anywhere in the scene. Each object can be: * Dragged * Rotated * Slightly resized (within developer-defined limits) The completed board is sent to another player who must find the five hidden objects as quickly as possible. The faster player wins. Solo Mode The game will also include a solo mode. Players can choose between: * Official boards created by me. * Community-created boards submitted by other players. The game should track statistics including: * Average solve time * Community difficulty rating * Number of plays * Completion rate * Player ratings Only a player’s first attempt on a board should count toward rankings and statistics. Player Ratings Finder Rating Based on how quickly a player solves boards compared to all other players. Example: “You solve boards faster than 84% of players.” Hider Rating Based on how difficult a player’s published boards are compared to all other published boards. Example: “Your boards take players longer to solve than 91% of community boards.” Content The completed game will contain approximately 20 unique scenes. Examples include: * Victorian Library * Candy Shop * Kitchen * Antique Store * Pirate Cabin * Toy Store * Scientist Laboratory * Bakery * Art Studio * Garden Shed * And similar environments. Each scene contains 25 available objects. The free version will include: * 4 scenes * 10 available objects per scene The paid upgrade unlocks: * Remaining 16 scenes * Remaining 15 objects per scene (25 total) Development Process Do not build all 20 scenes immediately. I want the project completed in phases. Phase 1 should consist of one fully completed, polished, production-quality scene with all gameplay working. Once I review and approve that scene and the overall quality of the game, we will proceed with building the remaining scenes. Artwork You will be responsible for creating all artwork required for the project. AI tools are completely acceptable (Recraft, Midjourney, Adobe Firefly, Flux, ChatGPT, etc.). This includes: * Background scenes * Hidden objects * UI graphics * Icons * Buttons * Menus * Visual effects * Any other artwork required for the finished game All artwork must be approved by me before it is considered complete. The artwork should be photorealistic and consistent throughout the game. The background scenes must be created in very high resolution so they remain sharp while players pinch-to-zoom on both phones and tablets. The scenes should be designed specifically for hidden-object gameplay with many believable hiding locations and minimal perspective distortion. Technical Requirements The game should be developed in Unity. It must support: * iPhone * iPad * Android phones * Android tablets Preferred backend: Firebase Required features include: * User accounts * Cloud save * Firebase database * Friend challenges * Community boards * Official boards * Save/load board layouts * Drag-and-drop object placement * Object rotation * Limited object resizing * Pinch-to-zoom * Panning around the scene * Timers * Player statistics * Leaderboards * Player profiles * Push notifications * In-App Purchases * Mobile advertising integration * Analytics * Settings screen The finished application should be fully functional and ready for public release. Publishing The selected developer will also be responsible for: * Configuring In-App Purchases * Integrating advertisements * Building release versions * Uploading the applications to both the Apple App Store and Google Play Store * Resolving any issues required for App Store approval * Assisting until both versions are successfully approved and published Experience Please provide: * Links to Unity games you’ve personally built * Links to games currently available in the App Store or Google Play * Your role on those projects * Your Firebase experience * Experience with multiplayer systems * Experience with mobile touch controls If you have experience building hidden-object games, puzzle games, drag-and-drop systems, object placement mechanics, or similar gameplay, please explain your experience. Please prove your experience by providing examples of previous work that demonstrates you have built similar mechanics or mobile games. Your Proposal Please answer the following: 1. Why are you the right developer for this project? 2. What similar games have you built? 3. Have you built Unity games using Firebase? 4. Have you implemented drag-and-drop, rotation, resizing, pinch-to-zoom, and touch controls? 5. Will you personally complete all work, or do you outsource any part of the project? 6. Approximately how long will Phase 1 take? 7. What is your estimated cost for Phase 1? 8. What is your estimated total cost to complete the entire project?
