It would have been nice to just stick with Siglus, but the cost of the license was prohibitive. One of the main things we had to forfeit is the Twitter integration, which was a fun gimmick in the original version. Other than that, we've had to scale back some of the menu options such as skipping back a line or changing opacity of the text box. Of course these are things that could be implemented in Kirikiri with enough time and resources, but the cost was out of the scope of this project. Still, I think the game looks great and functions well, especially for this price point
Edit// I just saw that Wildbreed responded above, and their post answers most of the questions! Thanks! ^^
