Interactive Website Activity Designer Needed

I'm in need of an expert in game or web design, able to create an immersive and visually appealing interactive activity for my website - something that can engage my audience and offer a relaxing, meditative experience. In essence, users should be able to navigate through a maze, virtually collecting mushrooms that trigger the display of calming mandalas upon collection.

Specific elements I would like to include are:

* psychedelic calming activity maze
* Abstract artwork (the meditative mandalas)
* Soothing and calming background music to augment the surreal atmosphere

Skillsets and Experience:

* Proficiency in game or interactive web design
* Ability to create vivid, surreal illustrations
* Experience integrating sound design with web elements
* A keen understanding of user experience design and the ability to make our activity fun and soothing.
