You're right. The concept is good, but no CG's. Also while I was studying the demo of it, I found out, that this game not only doesn't have visuals, but also demo is, I think, a modified full version. I know, this is normal for developer to modify full ver. of game to be a demo, but this one has most of the full game sprites and the only difference is in events.

Note: This is my speculation and I could be wrong about it. I posted a request because I can't get RPG MV to load the game to see and revert the changes made by dev/devs.
