I like how you show the world of Gensokyo from the eyes of an outsider. It really shows how dangerous that world is. Apart from that, I think a quick one screen tutorial on what button did what since it took me the longest time just to find the menu/save button. Other then that, I look forward to seeing how you develop this game.
Note: I played the v1.0.
