Why is there no multiplayer mode? like a word with friends style of battle your friends trying to guess simple Indonesian words for example like air=water or ubi=yam. Or some kind of multiplayer mode?
To answer your question "Why" I can only imagine the answer is "Because no one has put in the time and effort to develop one" I was hoping there was some kinda of public API so that we could develop one ourselves, but after a quick search, it looks to me like what used to be available might have been taken down. This project was last worked on 12 months ago, maybe it works.
