The book past crossing the puzzly lake was somewhat difficult to spot, it took me several attempts until it caught my eye when I had crossed the lake and not yet moved on. I suppose it's deliberate you can only make it out in the perspective of looking on the lake...
Neat story, nice level design. The gameplay being somewhat simple actually fits the whole impression of the game, IMHO.
The areal view when zooming out at the end is a brilliant idea.
