Great game and execution! And wonderful use of actions and connections. Already over 10,000 downloads and if it gets a feature this is gonna be a huge success. Not sure if the info screen is missing a background or if it was intended this way. But the text how to play for example is exactly above the COLOR title and difficult to read. This is on a 4s, no problem on the iPhone 6. And you asked, but no, there is no lag on either of this two devices. Hope this works out really good for you. Fingers crossed.
