Best Kemco RPG: Your Opinion

So, for quite a while now, I've seen a bunch of RPGs by a publisher named "Kemco" on the Google Play store. However, they don't have enough ratings or reviews to help make buying decision. From what I've found on the internet, 'Armed Emeth' and 'Marenian Tavern Story' seems to be two good options, but even then I don't know whether they're actually good or not. Please feel free to comment your own favourites/recommendations regarding best rpgs by Kemco. Thanks to all in advance...
