I've been searching for months but I couldn't find anything. It started with a boss fight that showed you how to fight monsters, then you could choose appearance, name, and after that it moved to you the castle where you could buy items/accept quests/add friends and more things (there was a Black Market, maybe it can help). At the beginning you had enough currency to buy a box that contained high level items, while exploring the monsters were a blue/pink aura that would attack you after being touched. In fights you can even attack by tapping, blocking with the shield or drinking pots for health. Can't remember much more, aside strange sword-like monsters or dragons hid in underground dungeons.
