Thanks!
Actually we're working in two related projects. The first one is a software to create visual novels and publish it as iOS apps. It's called Boken Engine and is available here. The other is a visual novel app using the former tool and we're still in the first steps. Its name is The Ikkai Saga, curse of blood, and is also available here. Feel free to take a look and provide feedback if you want.
Thanks again for the warm welcome!
