The idea is interesting, but I could not get this to actually play.
After I clicked "run game", I had Sapi read the instructions, I'm then told to click the screen and hit y to continue.
No matter how I simulated left clicks on the screen with NVDA, nothing more happened at all.
I dug out my mouse from the back of a draw, plugged it in and clicked away with the button, but was obviously not clicking the right part of the screen!
Rule one of designing an audiogame!
Please make sure it can be played with screen reading software.
