Great! I like this idea though I'm really bad at the game lol. I think it might become more fun if:
1. game start with smaller map 4x4 or 5x5, so player don't get lost with all those tiles to remember and gradually extend things.
2. more walkable road with more different things to happen. Now the path is too limited so the walk part is not that fun.
but I like this idea in general!
