Hey KSM! Thank you for your concern. Aa for your question, we're close at hand to finish an important feature to add to our current Chp1 to 3, so hopefully, once that's done, we can devote all onto chapter 4 android.
However, we had lost corrupted codes, bug and etc that have impeded what is supposedly an easy job, so I am deeply sorry, the build, while close to a demo that is checked within the team, is still not ready to the public.
We do our utmost to deliver the best reading experience for our crowd, So i ask for some patience so we can iron out the problems for the best experience as possible. Thanks for waiting, i swear it will show up, polished and fun to read!
