Ok boys and girls, the game is up on the App Store. Search for "Chroma Chords".
Once you have played it, come back here and start making refinements. As Dave said, the submission abilities will be down for a bit while we do some final tweaking, but you can start discussions in the anonymous forum or in any of the other forums until then. It shouldn't be too long. Even giving your general impressions of the game here is a great idea.
This is your canvas. Look at the game, scrutinize it and REALLY think about what could make it better, but be realistic. You only have two guys working on the game. While adding 6 new modes would be awesome, we don't have that kind of man power. Your submission won't be rejected based on "we can't do it", but if you want to catch the bug of, "OMG my idea made it into a game", it's best to make that idea approachable.
So get going! Start working on Chroma Chords! Make an account and visit the development forum
