Pretty good game. However I found a couple issues.
In the sorting minigame, if you place all the books on the shelves and you haven't sorted them correctly it's then impossible to take them out again to switch them.
The swiping down on the book order minigame is kinda tricky to deal with on computer since the game goes full screen.
Thanks for trying out my game!
As for the sorting minigame, its not a bug because you can swap one book with another so the game will never be blocked. But i am not sure why you mentioned that "it's impossible to take them out again" becauses i just tried to do that and i could pick up the books from the unfinished sections and place them somewhere else. But i suppose it's not obvious that you can swap books, so i will think about how to improve it.
Will try to optimize swiping books for web. Thanks for the heads up :)
