Thanks guys! Yes, it may have timed out as my friend needed to switch/upgrade his server. It's working great now!
As far as making money on this, the Kickstarter isn't to make money (we need a Mac so I can make the app.. so if you look at our goal, you know we aren't making money off it). We definitely wouldn't have done this if it were a just a clone. The point is to be educational: My friend (a composer) had the idea after seeing 2048 to use the Circle of Fifths as the tile progression to make a fun way of learning the circle of fifths, giving the game an educational/music theory twist, so we created it. And it's evolved into a game that feels very different. And if we do earn anything, it's because it's different - as you play, your low tile changes, it is possibly infinite, etc. And the audio is an incredible addition. And, it works - I can rattle off the circle of fifths in an instant
It's pretty awesome that it's getting attention. I hope it draws people to my friend's other educational/musical games. Our ear training game, Upbeat Bird (which is the same sort of idea as the Circle of Fifths - like another game but with an educational musical twist - it's like Flappy Bird but actually helps you learn the skill of musical timing), and a new one he's making called Rudiment Rock-It.
