VR Hero (Google Cardboard)

Overall game description
The player will evolve in a surreal environment to be determined later by the artists. He’ll evolve along a path guided by 2 border walls. In his path he’ll see elements he can “pick-up”. When doing so, visual effects will trigger that are related to the music. He’ll also be able to populate the world as he goes, varying the type of rewards he gets.
Playing the same song again will display to the player the last path he took, so he can follow this on again. He can obviously choose to change and go for another experience.
Link to the Theme: Ritual
The main idea is to play the game once per day as a morning or evening ritual. Being able to replay the same path over and over again can bring to the player a sense of control and serenity. He’ll be able to have the same experience more than once, and decide to change it anytime.

Able to trigger things in the 3D environment that will result in a variety of results that are predictable once known by the player

Time elements with the music beat (more or less hardcoded):
appearance of Nodes

Beat played in the texture of the border walls
Level description
The song is played as the player moves forward in the level. Each level is made of pieces of terrain which are connected dynamically by the code.
Each level uses:
A skybox
a few pieces of terrain
2 border walls that constrain the player into the gameplay space
Elements that can be used as Nodes in relation to the level’s theme
