Wait, where to buy the extra points? There is krone's atelier (which is the alchemist shop) the book store, and what else?
ps: remember to scroll down on the shops, since there are some locked on scenes there.
This game is really good, love the art and the writing, well polished system. Just starting to feel it may be too short, but something really good for a dev's first game. Hope they get to translated the missing scenes, that Krone is just the type of lewd-virgin-klutz that can make some excellent scene.
