I love the concept of a blind man's simon. I have never seen a game for blind people before on Newgrounds. This is probably because blind people would never visit a games site, but I won't subtract points because the game is kind of useless :P. After all, it's still entertaining for me.
Why I didn't give you a 5/5 is because the main point of the game, the sound, doesn't feel finished. It's not bad, but you could've included much higher quality sound.
It's most noticable in the tutorial, where the girl's voice changes halfway through the tutorial. The man's voice and the automated voice are way softer there as well. It'd be nice if the voice was the same volume throughout the entire game.
What does seem finished is the highscore. It's nice that you included a "ten" for every ten buttons you pressed correctly.
There is a bug there though. The highscore will always sound in the sound you got it in. It could work as a way to have different high scores for different people, but then you should have a different high score for every voice.
I am not at all disappointed by the fact that this game is completely black, but for an all-sound game the sound should be of higher quality. Everything works though, and for the original idea I give you bonus points.
