I'm looking for an experienced Unity developer to create a horror-themed escape room/survival game. The game will consist of 10 levels and is to be developed from a complete storyline that I have already created.

Requirements:
- 10 immersive horror-themed levels
- First-person perspective
- Storyline integration

Ideal Skills:
- Proficiency in Unity
- Strong game design experience, particularly in horror
- Ability to effectively integrate complex storylines into gameplay
- Experience with 3D modeling and animation
- Knowledge of sound design for an immersive experience

If you have a portfolio showcasing similar projects, that would be a plus. Please provide estimated timelines and any relevant experience you have in your bids.
