Working on an App "all by yourself" eh? Lol, I'm not criticizing though, having help along the way will definitely smoothen and speed things up.
So I'm curious and confused a bit by the game. I've read through various comments around here, and at first I got the impression that it might be some form of monster capture/training game, but then it turned out to be some "modern" type RPG, and you don't capture monsters. Do you think you could write a journal, or post a deviation on the general concepts for the mechanisms. By that I mean, how you'd play the game, if there are any battles and how they are executed. Is it going to be player vs. monsters? Is it going to be real-time or turn-based? Whether you collect items that you'd use directly in combat (like in TLoZ), or if they'd be just like some temporary power-ups. Are there any leveling mechanisms in the game? Does the player have health/energy/mana? Just some basic things.
