beta tester needed for Mac OS X 10.9 or 10.10 game

I need beta testers with a Mac with OS X 10.9 or 10.10 for beta testing INCIDENT AT KARROUSEL PARK. You are visiting Karrousel Park and are going to meet the friend of your choice. (You get to play with a loved one whose name you enter.) But you encounter problems in your search.

I am a professional writer and movie maker. Who is also a programmer.

I was a writer on the television series WISEGUY. I am David Curran IV on imdb.com. I sold westerns to Louis L’Amore Western Magazine. And I was admitted to the graduate program in computer science at the University of Montana with no background in CS. You can find my Crossword Cryptogram Solver for Mac OS X app in the Apps store. Or check out my internetdetectivegame.com

The program itself has so many possible situations I really need beta testers.

Blind Beta testers needed too. We want this to be easily used by the visually impaired.
