Cool project. The restarting idea is unique in it's own right, but it could also be layered into another game genre. Imagine an RPG where you can save the game, but every time you re-open the game it changes the world, enemies, items, or player abilities, adding a relatively unexplored element of RNG that I haven't really seen in that genre. I think it would also be cool to turn this into some kind of horror (not necessarily gory, just creepy) game where going to a tile slightly changes the tile you were at before (like the weeping angels from Dr. Who or something).
Hi, and again, thanks for the feedback.
The original idea for the game was actually going to be much more bloated in scope, including much of what you mentioned and a "hub" located at the center of the world where the player can sell artifacts and even send them to other players.
Some RPGs (like Yume Nikki) that have RNG affecting many things already exist. If not, well, it's only a matter of time until they do, I guess.
