I love the concept, sadly I got stuck really quickly, I didnt quite read the bit of dialogue that said something about the watchtower, and couldnt figure it out any further. 

Regardless, usually I don't like these dialogue type games, but the growing/shrinking mechanics actually kept me playing for quite a while, (even when stuck for several minutes). I also enjoyed how the large map also functioned as a sort of fast travel.  Well done!
