Unity Survival Puzzle Game Development

I have already outlined ten distinct survival-puzzle stages—each with its own mechanic, set of traps and logic-based challenges revolving around timing, sound cues and quick reflexes. You will take those concepts and turn them into a fully playable 3D experience, preferably in Unity, though Unreal is acceptable if you are faster there.

Here is the scope in plain terms:

• Build and light all 10 levels according to the flow and visual theme I provide.
• Hook up a simple but tight player controller (walk, jump, interact) and bake in death animations for every trap.
• Script the core logic—timers, randomised trap activations, level unlocks and basic save / load of progress.
• Layer in a minimal UI: main menu, level-select, restart screen and a soft checkpoint system.
• Optimise the whole package for smooth Android performance.

I will supply reference videos, sketches and a detailed description of every trap and puzzle so you can focus on implementation. Experience with triggers, animation events, audio cues and mobile optimisation is essential; shader or lighting polish is a bonus.

Final delivery: an Android-ready build plus the complete, well-commented project files so I can iterate later. Let me know which engine and version you prefer and share a quick clip or repo link that best shows similar work you have done.
