Audio free walking

Thinking about my wife that have low vision I had the idea to create a fully base audio game.

I'm trying to create a game app for visually impaired people. non-disabled people can play too but the game is all audio based. like a 3d environment that you can walk around and interact with things. In this project in the experimental state, I put some coins that emit a soft sound that you can collect if you want. there's a dog that can help you with that. the commands are simple. double tap to summon the dog. double tap again to have him look for a coin. when he finds it, there is a probability that he will bark. if he doesn't bark you can double tap again for him to bark so you know where he is. there is a person with a guitar who walks around the environment and stops from lake to lake to play music. the songs are covers of some songs by the elder scrolls. so all i ask for is donations so i can continue the project. all rights to sounds are owned by Bethesda softworks. I am under protection of (fair use)
