Three.js Developer / 3d Game Designer for Endless Runner

I'm looking for a developer who can build a simple but fun browser-based 3D endless runner using Three.js.

Game concept:
Character runs forward automatically
Move left/right to dodge obstacles
Collect items for points
Game over on collision
Restart without refreshing the page

Visual style:
Clean low-poly or stylized look – no AAA graphics needed.
What matters most is that the game feels good to play and looks presentable.

Nice to have (but not required):
Mobile support
Sound effects
Particle effects
Increasing speed / difficulty over time
Multiple obstacle types
High score saving (localStorage or similar)
If the project goes well, there will likely be more work afterward.
