Advantages: great music, especially sneezes! Creative plot, perfect graphics - simple and elegant.
Things to improve: too fast at the beginning. I started 3 times until I understood what I had to do. Also, I would add a leaderboard or a score to reach (e.g. if all the town suffers - 1000 people-you are the winner)
General impression: fantastic game! And I am waiting for the new games;)
