Looks pretty awesome, but I hate those RTP characters and tiles. You have original portraits and monsters and systems, and truthfully, changing the game out of that RTP style would make this look a lot like a professional game, rather than an RMVX game. Sorry if that sounds rude at all, but the RTP is my greatest nemesis.
But, again, this looks pretty awesome. Can we see a demo anytime soon?
PS- I suggest not mentioning the difficulty and grind-ness as the third sentence of your post; it was one of the first things I read, and the developer telling me that the game will be excruciatingly hard right from the bat makes me not want to play. But I kept reading and changed my mind.
