I’m planning a new puzzle game for adults that runs in true endless mode—no discrete levels, timers, or forced stops, just an ever-increasing challenge that tests how far the player can go. The core loop should be simple to learn yet difficult to master, with difficulty that scales smoothly so engagement never drops. My preference is a cross-platform build (Android and iOS), and engines such as Unity or Godot fit the bill nicely, though I’m open to anything that compiles cleanly for both stores. Visuals need to feel mature: clean typography, restrained color palette, subtle animations, and nothing overly cartoonish. Sound design should follow the same understated style. Deliverables • Playable endless-mode prototype with complete core mechanics • Polished UI/UX, subtle animations, and background audio • Local scoring/leaderboard system (online integration is a plus) • Hooks left in place for ads or in-app purchases • Fully commented source code, project files, and build instructions Acceptance criteria • Installs and runs crash-free on current Android and iOS devices • Maintains a stable frame rate on mid-range hardware during 30 minutes of continuous play • All assets are either original or cleared for commercial use If you’ve previously shipped puzzle or endless titles, please include a link or build so I can see your style in action. Excited to collaborate and turn this concept into an addictive, polished game.
