So the concept and models are good. Animation is actually not that bad either. There are 2 bits of feedback I have for the dev if they keep an eye on things here:
1. So far, this does NOT need to be in RPG Maker AT ALL. Everything so far can be done in Ren'py and probably a lot nicer. (I could help you out if you would like, I have some experience in Ren'py)
2. If they decide to stick with RPG Maker, you need to have some system to tell the player what to do next. Some kind of quest log or something.
Lastly is just my general recommendation to ALL games on here, you eventually would want to get a Gallery implemented. It's ALWAYS a nice thing to have.
