First impressions - music is excellent.
In game graphics are very good - however, IMO the blocky text and buttons on the main pages/menus don't seem to "fit" with the rest of the game style. It looks like a retro game interface has been bolted onto another nice looking game.
Can I check - on chamber 6 - should I be able to click on the key to collect it? As I can't on my iPad 2. Or do I need to do something more obscure?
Thanks, I'm gonna let the musician know about your praises

About the menu and font:
Frankly said, I wanted to achieve exactly what you described. A retro looking menu/font within a HD game -> some sort of style clashing. But now I know that not everyone is as appealed by that as I am.
About chamber 6:
You can touch the key and take it as soon as it's laying on the floor. Now you only need to get the key down

There's also a video walkthrough in case you're stuck and on the verge of insanity
