Cute little game and I also managed to get through without issues. I wish there was some sort of tutorial or similar indicator as what each book does as it is kind of hard to play even when you know what affects the books. There is also some issues I find when trying to place the books in place, if its not directly in the boxes (ie a little bit of the book is off the edge of a box) it wont place it in properly, this can be annoying as it slows you down alot when it could just snap into place. Very enjoyable game!
