Took me a bit to see how the main menu works. Cool though!
And got my first two books. Card Catalog issue, make it that clicking where you get mouseover text opens the drawers too?
If you wanna be diagetic, maybe make the drawers bigger and write the words length wise instead of top-to-bottom so you have enough space instead of needing to mouse-over?
This is already a full-screen game, so you have all the screen real-estate and don’t have to just zoom in on tiny graphics for a menu?
