Wow, I did better than I expected! Very original and it truly tests ones hearing! I have trouble with the lower pitches, so I usually missed the bugs at the bottom.

Seems like that was a common issue, it may have to do with what headphones you were using to play, the pitch is pretty low. With the headphones I used during development I was able to hear it just fine but then after I started getting comments about that and tried it with a different pair and got the same issue. I'm glad you did well though, and that you appreciated the originality! Thanks a lot.
