3D Elemental Endless Runner

I’m building a lively, cartoonish 3D endless-runner for Android where the hero sprints through Cityscape, Forest, and Desert tracks while hurling elemental attacks. A tap or swipe should let the player choose Water, Flame, Wind, or Thunder, then launch the chosen power straight down the current lane to clear oncoming enemies.

Core gameplay
• Continuous forward run with simple lane-switch controls.
• Score counter that rises with distance and kills, and an adaptive difficulty curve that tightens spawn rates and speed over time.
• Enemy types able to absorb damage and, if they reach the player, trigger a fail state with a quick restart.

Monetisation & services
AdMob is the ad network I need. Please wire in rewarded ads. All placements must respect Google policy.

Visual & audio tone
Keep everything bright and exaggerated to match the cartoon style—chunky models, vibrant textures, punchy VFX for each element, and upbeat background tracks that change subtly between the three environments.

Deliverables
1. Unity project and all source assets (or your preferred engine if it exports to Android with the same feature set).
2. Signed APK ready for installation on Android 10+.
3. Simple README explaining build, keystore setup, and where to swap ad IDs.
4. Optional but appreciated: a short video capture or GIF demonstrating each elemental attack.

I’ll test on a range of mid-tier phones; smooth 60 FPS and no crashes are the acceptance bar. Looking forward to seeing your approach to fast, fluid elemental combat in runner form!
