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!

I managed to walk through all levels without crashing (maybe it has something to do with placing two red little red books next to each other) and it was pretty interesting! Though it took some time for me to figure out that bigger books sort of charge red ones and make them cover space and that I have to make gaps purple.

Game Visuals, had the same issue that Huginn Hrafn mentioned. Very promising game idea though, great job!

The visuals are just awesome, the frog looks really cute :)

I downloaded it and started playing, but unfortunately the game freezes on the first level and I have to force close it :(

If you fix it, let me know, I'll definitely try again.
