I’m building a lightweight mobile survival game and need a developer who can take full ownership of the code side while I handle the visuals with my graphic designer. The core loop centres on combat and defence, so you’ll be implementing enemy AI, wave spawning, simple upgrade systems and tight, responsive controls that feel great on touch screens. The look and feel will be bright, fun and unmistakably cartoony; I’ll supply all sprites, UI elements and effects, and I’ll count on you to hook them up, optimise draw calls and keep the build size lean so it runs smoothly on both older Android phones and current-gen iPhones. Google AdMob integration is a must. Rewarded video and interstitial placements should trigger at clean, logical moments in the session without disrupting flow. Please set up test IDs, mediation and basic analytics events so we can verify impressions and retention during soft launch. I expect the project to be built in Unity (or another proven cross-platform engine you’re comfortable with) and delivered ready for submission to the App Store and Google Play, including platform-specific icons, splash screens and privacy strings. Key deliverables: • Complete Unity (or equivalent) project with documented source • iOS and Android release-ready builds (TestFlight / APK) • Integrated AdMob ads, testable in production mode • Basic read-me outlining build steps, SDK versions and any third-party plugins Acceptance criteria: – Smooth 60 FPS on a mid-range 3-year-old device – No critical crashes after 30 minutes of play in TestFlight and internal Play testing – Ads load and dismiss reliably every cycle If you love squeezing fun gameplay into a small footprint and can communicate clearly with an artist, I’d love to hear how you’d tackle this.
