Cartoony Endless Runner Mobile Game

I want to bring a bright, cartoony endless-runner to life—think Subway Surfers sprinting through a lively urban cityscape, all backed by upbeat, energetic music and snappy SFX. Unity or Godot are both fine with me as long as the final builds run smoothly on Android and iOS...
