Cool, thanks for the feedback.

The menu buttons do have an invert effect when you tap them, but it might be too subtle. There's also audio feedback when you tap a button, but that doesn't help if you have your sound off.

Right. Most buttons I did notice feedback. It was mostly when I first entered the app. Didn't see feedback on the button in the splash screen or the screen immediately after (if I recall correctly). And yes, I had sound off.

Also, when posting to HN. It would probably be best to organize an up vote campaign. I'm not saying game HN to get on the front page, but getting some initial up votes and comments will help you to get others interested in a headline they might otherwise ignore in the "new" section.
