O my goodness, how did you do this in 2 weeks, and how it is that you do not have more raitings??? This is the first time I am giving a game 5 stars for eacg category!! It had everything top! Ready to upload to Google Play, amazing job! I stopped playing just because I wanted to have a look at the other games that had less ratings if I find there something interesting. And your game blew me away! You got a new follower :)))

Very smooth and enjoyable puzzle game. Impressive that it is programmed in pure JavaScript. Thanks for sharing your code!  

Smooth gameplay, and the graphics and sounds pulled me in right away. Would love to see this expanded!

Interesting game it seemed like books were disappearing on their own   but maybe I misunderstood the gameplay.

The gameplay is great!
I found the graphics a bit inconsistent. Some fonts were quite small, the merge animation was a bit confusing at first? Also there was a lot of information on the screen, maybe I just prefer a simpler UI :) 

Really nice background graphics and animations, makes a simple game a whole lot more enjoyable.
