Well done Nathan, I enjoyed your game immensely. I felt a surge of excitement when I unlocked the one building only to find it was empty! I had to go back a few times to the first building to learn all that could be learned there because I rushed out. I, for one, enjoy the pacing of the game to include the walk speed and the bridges / door lock.. it sets the pace well and also is an incentive for knowing all you need to know before going back and forth. I would have enjoyed more sounds, I'm not sure I heard anything other than the button clicks for the puzzle.
Great entry!
